SRU Bullpup Chassis

Review

  SRU Precision has brought out some pretty nice AR bullpup conversion kits. If you have been thinking about getting a bullpup, the SRU kit might be the way to go. The SRU AR15 bullpup chassis comes in a number of configurations to help you choose the right system for you.

  To sum up the SRU Bullpup Chassis, it is a 2 piece shell that wraps around an AR15. Not the full AR, just a mil-spec receiver and an upper. There is a stipulation on the style, or type, of upper receiver you use. A standard one can be used, but you will need to get a short recoil system. If you do not want to go this route, any bufferless upper should work. These include the Jakl, BRN-180, or what I used, the Foxtrot Mike Gen 2. The 2 piece shell is made from a carbon fiber infused polymer, which gives it extra strength and rigidity. 

  Installation of the SRU chassis can be time consuming. There are a lot of screws and pieces that hold the SRU Chassis around the AR lower receiver. Using the Foxtrot Mike upper made it a little bit easier. Luckily SRU has some detailed online instructions. Let’s just say that this is not the easiest kit to assemble. First, you have to take out most of the SRU Chassis’ screws. Then you will have both sides apart to start putting in the parts. Next install the short buffer tube into your lower receiver with the proper parts for your chosen upper. Then install the lower receiver assembly into the chassis. Make sure you have removed the trigger guard from the bottom of your receiver, or the SRU chassis will not work. Adjust the trigger travel screw. The SRU chassis uses a trigger linkage, which is why it needs adjustment. There is also a QD forward mount that needs to be installed and adjusted. This forward mount holds the bottom of the upper receiver in-line with the chassis. Now you can reassemble the two halves. Trust me, I simplified this for the review. I probably had the chassis apart 3 or 4 times to get all the parts adjusted correctly.

  The trigger system is what really makes the SRU Bullpup Chassis shine. Since the SRU kit uses an aluminum trigger linkage, you get a good trigger. Bullpups are notorious for having bad trigger pulls, but SRU seemed to solve this problem. Another advantage to the SRU kit is that you can choose any AR15 trigger to install. That is because the trigger is actually in your AR receiver at the rear of the bullpup. The SRU kit does add about 1 pound to the total trigger pull weight. I used a Black Talon Tactical 3.5 pound trigger and it ended up right at 4.5 pounds. SRU made the chassis with a flat trigger and a single sided safety. These are pretty decent. If you do not like them, you can change them out for any mil-spec trigger shoe or any AR safety that you like, including ambi ones. You can also take the triggers pre-travel out by shimming it, the instructions just don't explain how to keep the shim in place. 

  The SRU Chassis does not come with a pistol grip. This is not a big deal. I installed a Thril pistol grip because I like them. Even though it worked well, I soon realized that a more vertical grip would work much better. This is because there is not much room between the pistol grip and where the chassis drops down to accommodate the magazine, and the magazine itself. It is pretty minor, and I still have the Thril grip on it. I also found the length of pull to be long. SRU states 15.3 inches, which seems about right. If you have short arms, it might be harder to reach the trigger than with a standard AR. 

  I should probably mention a few differences when using the SRU chassis. The mag release comes to mind first. It uses a lever style behind the magazine, similar to an AK style. It works well for me, but it did take some getting used to. Another thing to note is that you may need a higher than usual optics mount. This is because your cheek rests on top of the receiver, on the little pic rail cover SRU supplies. First I mounted up a red dot. Then I went to the ZeroTech Thrive HD 1-8 in a standard cantilever mount with a riser. Lastly, a 1.93 Geissele mount was added. It put the scope up high enough to use without a riser. 

  Foxtrot Mike was kind enough to send me the upper for the SRU Bullpup. That way I could just drop in the upper and not have to worry about short stroke kits. The upper Foxtrot sent is their brand new monolithic style upper receiver. It uses their forward charging system and a built-in buffer/spring recoil system. This particular monolithic system uses a 1 piece barrel, gas block, and barrel extension. It also uses a 308 size bolt for more strength. The Foxtrot upper has a full 16 barrel and comes with a threaded on A2 flash hider. This system with the SRU chassis made a really nice bullpup. The barrel sticks out just far enough so that you do not feel like you are going to shoot your hand off. 

  Now it is time for the love-hate experience. Okay, more love than hate. I was not sure how I would like this bullpup in the beginning. It surprised me. I really like how compact it is. The forward charging upper with the SRU kit makes it easy to cycle with the gun up on your shoulder or while running the gun. Magazine changes are fairly quick, even if I can do an AR mag change faster. The whole thing weighs 7.25 pounds without a mag or optics. So it handled pretty decently for me. Plus the weight is toward the rear, so you are not trying to swing a heavy weight back and forth between targets. Since I did not shim the trigger, there is a bit of take up before you get to the trigger's break. I just did not want to take it apart again to shim the trigger. You will also notice in the pictures that the scope mount is turned around backwards. This was done on purpose so that the physical mount would not get in the way of the forward charging handle. You can turn it around to the normal position and it will work. I just didn’t like my hand rubbing on the mount. 

  If you like bullpups, or maybe just want to try one out, the SRU Bullpup Chassis kit may be a good fit. The quality of the kit is top notch. It probably has one of the best bullpup trigger systems around, at least in how it feels. The polymer chassis feels good and not cheap. I ended up really liking the SRU bullpup chassis. Head over to SRU and check it out.

Monolith Review

  A little over a year ago, Global Ordnance teased their Monolith rifle and pistol. As is usual when introducing a new rifle, it took some time to get them into production. But alas, here we are. I was one of the first few to receive one to fully try out and review! The Monolith rifle has a ton of features over your standard AR15. I think you will like hearing about them. 

  To start with, the Global Ordnance Monolith is not your fathers AR15. Yes, most of the parts are semi-interchangeable with a standard AR15. Some of those compatible parts are the complete upper receiver assembly, trigger, and the safety selectors. For clarification, the Monolith upper can be used on a standard AR, but a standard AR upper can not be used on the Monolith. Other parts are proprietary, but in a good way. 

  You might ask what is in the name “Monolith”? That is where some of the improvements come in. The Monolith is designed with a single piece barrel assembly. So the muzzle brake, gas block, barrel, and barrel extension are all one machined piece. Unlike an AR15 where those would be four separate pieces. The Monolith also utilizes a 45 degree gas tube that uses a fuel injection style fitting. This eliminates needing a roll pin to hold the gas tube in place. So by re-engineering these parts, Global Ordnance has made a stronger and lighter barrel assembly that has less attached components, thus making a barrel system that has less failure points. 

  The first version of the Monolith comes with a Keymo style muzzle brake. As mentioned, this muzzle brake is machined into the barrel, so it is not removable. The Keymo muzzle brake was selected because it is a common muzzle device that can be used with a bunch of different suppressors. It also works very well as a muzzle brake, if you are not wanting to mount a suppressor, or live in a state that does not allow them. Threaded barrel options may be available in the future so that you can install your own muzzle brake of choice. 

  On the rear of the one piece barrel is the barrel extension. The barrel extension is what the bolt locks into to keep the cartridge in the chamber while firing. It also has cut outs, or feed ramps, machined into it. These help guide the cartridges out of the magazine and into the chamber. The Monolith uses an AR10 size extension. This is larger than an AR15 style, so you get more strength. The barrel is made from 4150 ordnance grade steel (the stuff they use on machine gun barrels) for added strength and barrel life. Therefore the extension is also 4150 since it is machined with the barrel. The barrel assembly/barrel extension is then thermal fit into the upper receiver. This is also done for strength, but also gives better accuracy than the slip fit of most AR15 barrels.

  Instead of the standard AR style recoil buffer system, the Monolith uses a bufferless system. The recoil system, as well as the bolt, are housed inside the upper receiver. This allows various things, but the main purpose is to get rid of the AR15's buffer tube.

  By getting rid of the buffer tube, one can install a true folding stock. Global Ordnance went one step farther and built the folding stock mechanism into the firearms lower receiver. The stock folds to the left side of the rifle. This gives you a rifle that can fire with the stock folded, all day long. The stock is a F5 ACR style modular stock system. The Monolith's stock is adjustable for length using some side buttons. It also has a little cheek piece that can be popped up higher. This is nice if using magnified optics. Inside the stock is also a little storage compartment for batteries or whatever. You can only access the compartment when the stock is folded. So if the stock is in the shooting position, those batteries are not falling out. 

  The manual of arms on the Monolith is a little different from a standard AR15. The Monolith's charging handle is a folding lever, forward of the receiver. Not the rear style like in that standard AR I keep mentioning. So the charging handle sits in the rifle's handguard, toward the top picatinny rail, on the left side. It folds forward when not in use. Otherwise, the handguard is a pretty standard MLOK style with a top rail. The charging handle can also be swapped over to the right side. The forward style charging handle works very well and is not hard to get used to. 

  One of my favorite features of the Monolith is that it is full ambidextrous. I already mentioned how the charging handle can be reversed, but there is way more. To start with, the lower receiver has full ambi controls. This includes the mag release, bolt release, and the safety. The safety comes with a short and long paddle, they are reversible to either side. If you want to take the grip off, you can change the safety from 90 degrees to 45. Both sides of the magazine release use a square button. The bolt releases are extended on the bottom to make it far easier to lock the bolt back. A key feature to the Monolith is the ability to drop the open bolt by just pushing down on the dust cover.

  There are only a few other things about that Monolith that need to be shared. First up is the trigger. It is a flat mil-spec trigger. It is slightly better than a standard mil-spec trigger. Its pull weight is about 5.5 pounds on this rifle and feels like it has a little less creep. Global Ordnance also spec’d out a B5 grip. The grip has good texture and matches the rifle nicely. Lastly, the Monolith only weighs 5.82 pounds out of the box! With a Primary Arms 1-10x28 and a full magazine, it only weighs 7.8 pounds. So the whole package is pretty light.

  The Monolith is a great rifle, but it does have some quirks. It comes with an extra recoil spring assembly. The extra is supposed to be for suppressor use. However, when I ran the Monolith with a suppressor and the “suppressor” spring, I had 2 short strokes and a failure to lock the bolt back on an empty magazine. This was in about 3 magazines. I switched back to the normal spring and it worked great, even with the suppressor. I ran around 200 rounds suppressed, after switching the recoil spring back to the original one. Other than those failures, the Monolith ran like a champ. Another problem I ran into was that I could not pull the charging handle back far enough to charge the rifle. After inspection, the charging handle carriage was binding where it goes through the receiver. I smoothed it out with a round file and have not had any problems since. The manufacturer has now since put a chamfer on the part, eliminating that problem. Lastly, the stock can flex a little if you really pull the rifle back into your shoulder. I never noticed it while shooting the Monolith, only when I was dry firing it. 

  Now to the good stuff. I really like how the Monolith shoots. The lightweight really makes it a joy to use. You can move from target to target quickly or get reasonable accuracy out of it. It averaged from 1.4 inches to 2 inches at 100 yards with almost any ammunition, from 55 grain up to the 75 grain. Global Ordnance supplied some 69 grain match ammo for the review, it grouped about 1.6 inches. I also really appreciated being able to drop the bolt by just pushing the dust cover down. The folding charging handle also works well as a kick stand so your hot suppressor does not touch the table and melt stuff. I also appreciated the folding stock, it is nice to have folding abilities in a rifle. Probably my favorite aspect of the Monolith is the one piece barrel assembly. Not only does it eliminate parts from the rifle, it is just a cool piece of engineering. 

  To improve the Monolith, I did add a few parts. Because I did not care for the trigger, I installed a flat Geissele SSP trigger courtesy of Primary Arms. This made a drastic improvement in how it feels and shoots. I am just not a fan of mil-spec triggers. During the testing, I also had a Holosun red dot mounted on it at first. Mainly it ran the Primary Arms SLx 1-10x28 with their Nova fiber dot reticle. This was a great choice for the Monolith. It let me do accuracy testing at 100 yards and do fast work up close. The Monolith was fine by itself, I just like better triggers. Plus, you can’t really do much without some sort of sight.

  If you are looking for an AR that is not an AR, but better, the Global Ordnance Monolith might be it. This rifle has all the features anyone could want. Plus the monolithic barrel assembly is just a great improvement. I enjoy the lightweight and ambi features of the Monolith too. Definitely go take a look at the Monolith, especially if you are looking for something different than your standard AR15.

Walker Defense Dark Matter BCG

Walker Defense Dark Matter

High-Polish DLC BCG Review

  The heart of an AR15 is the Bolt Carrier Group or BCG. A quality BCG can make your rifle perform like a champion. A mil-spec BCG might work, but will not perform as well, especially if you are trying to get the best performance out of it. Walker Defense Research has released their Dark Matter Bolt Carrier Group. This highly polished, fitted, and DLC coated BCG is of the utmost quality.

  When looking for a Bolt Carrier Group, either to replace one or for a new build, there are things to consider. Do you want cheap, or are you looking for top quality that will last forever? The Walker Defense Dark Matter BCG is in the top quality group. To start with, it is a M16 style full auto carrier. So if you are fortunate to have a full auto M16, M4, etc, it will work with that. More important is the fact that the M16 carrier has the full mass, which allows it to run more smoothly, at least in my opinion. This Dark Matter carrier is also made from 8620 tool steel for a lifetime of use. 

  The Dark Matter BCG has a bunch of hi-end specifications. Some of these I will describe more in depth later. This BCG is for standard calibers and for use in direct impingement guns. These include 5.56/.223/300 blk, etc. It weighs 11-⅝ ounces and is made to true mil-spec dimensions. On the front end it has a C158 bolt that is magnetic particle inspected and high pressure tested. The 4130 gas key is properly staked using Optimized Carrier Key Screws (OCKS). These screws are deeply knurled to allow the staking to dig in, making them almost impossible to come loose. Lastly, the Dark matter BCG is DLC coated.

  Walker Defense is all about small batch quality. Here is what they have to say about the Dark Matter BCG: “We’ve always leaned into our advantage as a company specializing in small-batch production, but we’re taking it further. Those extra touches of quality add up and give us the ability to do things that larger companies just can’t. A few quick tangible examples of this:

Each carrier is matched by hand to each bolt and cam pin to prevent tolerance stacking and to ensure ideal, consistent fitment as the bolt cams back and forth.

We also pair each bolt with its firing pin to confirm adequate protrusion for reliable primer ignition.

Using OCKS screws for ultra-aggressive staking of the gas key, so it won’t loosen at high round counts”

Those are just a few things Walker Defense does to give you the best BCG around.

  DLC, or Diamond-Like Carbon coatings have been around for a while, but the Dark Matter BCG takes it to a new level. DLC coatings by themselves are extremely hard, corrosion and wear-resistant, and very slick, which gives them low coefficients of friction and superior dry lubricity. Walker Defense takes this up a notch by aggressively polishing the bare metal, before it is coated. As with most machined parts, a BCG is only as good as its base metal. This polishing is a very labor intensive process which makes the Dark Matter BCG super slick and mirror-like shiny. Then after a high quality dark black DLC coating is applied, they polish the DLC coated BCG again. This makes the BCG even more slick (and also hard to take pictures of because of the mirror finish it produces). By polishing the BCG before and after coating, you get an extremely smooth surface that carbon has a hard time sticking to. Cleanup on the Dark matter BCG is super easy. One can literally just wipe it off with a rag. Carbon just doesn’t stick to this BCG.

  I am using the Dark Matter BCG in a 300 blackout AR pistol. This pistol ran suppressed for around 60% of the review. Why does this matter? Because the pistol gets a lot dirtier. The upper on this pistol is nothing special, just your off the shelf AR upper receiver. Before installing the Dark Matter BCG, I was running a Mil-Spec BCG. After I installed the Dark Matter BCG I could tell a smoothness difference. Not just in how the gun cycles under use, but also when hand cycling the action. The AR pistol is just way more pleasant to shoot now. Another thing I noticed was that the brass ejection was more consistent than with the mil-spec BCG. I attribute this to the action cycling smoother. After around 800 rounds, I can’t even really notice any wear on the Dark Matter BCG, a testament to that fantastic polished DLC coating. 

  The Walker Defense Dark Matter BCG is slick, pun intended. This BCG is of the utmost quality. It has all the standard features you would want in a high quality BCG: MPI and HPT tested, DLC coated, quality base metals, and true mil-spec dimensions. That does not even count the “extras” Walker Defense puts into these. One would be hard pressed to find a better, or smoother BCG. The price on these is very reasonable for what you get, definitely a high value to price ratio. If you are looking for the slickest, highest quality BCG around, definitely go look at the Dark Matter High Polished BCG from Walker Defense. These are literally super slick.

Barrel Review

  Have you ever had something so long that you end up going down a deep hole of what you want to do with it? Well I did with this barrel. I had it on the shelf, looked at it, and wanted to do so many things with it that it soon became a thorn in my side. Now this thorn is me, not the barrel. The Tactical Kinetics 300 blackout barrel is fantastic. It is well machined and looks better than some of the big name rifle makers barrels. Tactical Kinetics sent me this barrel for review almost a year ago. No excuses but life happened and that's why it has taken so long to do this review.

  I mounted the barrel in a no name, unbranded, upper and put it on a PSA lower that has a Sylvan folding adapter. Fitment of the Tactical Kinetics barrel was plain and simple: great machining, the coating in the barrel looked good, and the threads for the barrel nut were properly machined. I ended up taking it apart three times, changing out gas tubes, gas block, and finally going with an adjustable gas block from Velocity Precision. 

  After completing the first build, it ate everything I fed into it when I was firing for reliability. Except for the subsonic 220 grain ammo I had for testing. I knew this was either a gas issue or a buffer weight issue. So back to the drawing board. Build two was now completed and the Tactical Kinetics barrelled upper was placed on a SBR lower. In a bout of frustration, it still would not run my subsonic ammo. So for the third and final time, I reassembled all the same parts. The rifle worked with all my ammo now. What a relief. Then I realized everything I had done, when I put all the parts together, was my fault. We won't go into that now.

  At the range, I took the little 8.5” barrel out and sighted it in at 25 yards. It fired all different weights of ammo. The barrel grouped best with 204 grain subsonics with a suppressor attached to it. I only had a red dot on top and was shooting from a rolled up jacket. Then I went to dumping magazine after magazine through it to see what it would do when it was hot. Well there was not a lot of shift in impact, maybe 1” and that was probably me. The accuracy was far better than a Bear Creek upper that I have with the same length barrel. Groups off the rolled up jacket were about 2.5 inches. For me and my intended use of this rifle, I thought it was great. 

  This is my first barrel review and it has been hard to do. What I can say about the Tactical Kinetics barrel is that the machining is quality, the rifling was good, and it grouped well. I know comparing it to a BCA upper is not fair, but that is all I had. 

  Would I recommend this company to buy from? Damn skippy I do. I already have a wish list going for a few 6.5 Grendel barrels they offer. Tactical Kinetics is one of the company’s you want to do business with. Quality parts, great customer service, and patience for not sending headhunters out for the review.

Sharps Bros Livewire AR-15 lower receiver review

Written by: Buddy Murphy

  This is a review of the Sharps Bros Livewire AR-15 lower receiver. Yes, these are the same guys that make lowers with skulls, warrior helmets, or other goofy things on their magazine wells. But when they get serious, they make a quality, functional piece of kit.

  One of the first things you'll notice is the heavily flared mag well, which not only looks great but also makes reloads faster and more intuitive. The ambidextrous bolt release is another welcome feature, providing ease of use for both right and left-handed shooters. This particular design for a right side bolt release has the perfect amount of force needed to release the bolt. Some other receivers take too much effort to release the bolt, forcing you to move your hand off of the fire controls, like the PWS Alpha.

  The right side bolt release is especially useful for me (right-handed shooter) when shooting CMP (Civilian Marksmanship Program) courses of fire. The first and last stages are single load stages. Meaning, you have an empty magazine in your rifle (or a specialty mag), you drop a round into the ejection port, close the bolt, and fire your one round. You repeat that 10 or 20 times depending on the stage. This forces you to break position between each shot. By having the bolt release on the right side, I can hold my rifle against my shoulder with my left hand, and get another round, drop it in the rifle, grip the rifle with my right hand, and close the bolt, minimizing my movement between shots.

  The transition between the integrated, oversized trigger guard and the magazine well is stepped, giving it a distinct and clean look. The threaded bolt catch pin and rear takedown pin recess also add to its overall precision and durability.

  As of July 2021, Livewire has undergone a significant upgrade, it is now made from a forging. The process begins with a 7075 aluminum billet, which is heated to 800 degrees and then forged into a near-final shape using a custom tool in an impressive 4100-ton press.

  Post-forging, the receiver undergoes final machining on CNC machines. This reduces material costs and machine time without compromising quality. The result is a receiver that feels incredibly robust and well-finished, with every detail meticulously crafted. The anodized black finish, done to MIL-A-8625 standards, ensures durability and a sleek professional look.

  Putting the lower parts in the receiver was a standard affair except for the left side bolt catch. Instead of a roll pin holding the bolt catch to the receiver, it has a small hex-head screw. This makes it much easier to attach the bolt catch than tapping in a roll pin. Also, before you attach the bolt catch, you must insert the included transfer bar. The transfer bar allows the bolt release, on the right side, to push the bottom of the bolt catch toggle (causing the top to move in towards the receiver as if you pushed it), releasing the bolt.

  In summary, the Sharps Bros Livewire AR15 receiver delivers on every front; strength, precision, and aesthetics. It’s a top-tier choice for anyone looking to build or upgrade their AR15 with a receiver that truly sets itself apart from the rest. While it maintains the classic AR15 aesthetic, it brings its own unique flair and functionality to the table: like the oversized integral trigger guard, beveled magazine flare, and ambidextrous bolt release. It is fully compatible with mil-spec parts and magazines. Weighing around 8.7 ounces, it strikes a perfect balance between weight and durability.

FOXTROT MIKE RANCH RIFLE

foxtrot mike

ranch rifle review

  I had great pleasure in getting one of the Ranch Rifles from Foxtrot Mike after SHOT Show this year. When I saw one, I was intrigued with how it looked, how it functioned, and the machining that went into it. I liked the fact that it was 50 state legal, was set up like a familiar 870 shotgun, had a forward charging handle, and still took standard capacity AR mags. 

  The 16" barrel version of the Ranch Rifle provides a balanced platform for out to medium-range engagements. The rifle features a **bufferless design**, which is one of the hallmark innovations of FM Products. This eliminates the need for a traditional buffer tube so that other stock options can be had. Hence the addition of the **Hogue 870 stock**. Which is a nice touch, offering superior comfort and control.  For shooters who are familiar with their old 870 shotgun feel, this rifle will fit like an old glove. Especially during extended range sessions. The stock provides excellent support and helps with recoil management.

  The charging handle, which is housed in the handguard on the FM Ranch rifle, can be changed from the left side to the right side. This is so you can choose which side you want to charge the rifle from. The handguard is also Mlok compatible so you can add your favorite accessories to it. They also offer a slap mod. This makes the charging similar to an HK. I did not have this option on my rifle, but it is another feature you can get to add to yours. 

  The 4-Port Muzzle Device is designed to reduce both muzzle rise and recoil, making quicker follow-up shots and better overall control of the rifle. This is especially helpful in rapid-fire scenarios where muzzle control is essential. The device works well in combination with the rifle’s bufferless system. The 16" barrel ensures that the rifle can perform effectively at varying ranges, from short to longer ranges. The rifle is chambered in 556 Nato. The use of Standard AR mags a plus.

  Shooting the Ranch rifle was a complete joy, once I figured out the manual of arms. Things are in a few different spots than your traditional AR rifle. I had a problem trying to reach the mag release to do fast reloads. But this is a ranch rifle and not a tactical rifle. Not saying that you can't use it as such. I had topped it off with an Atibal green dot and ran close to 2K rounds through the rifle, both at the range and at a class. When I first started shooting the rifle, I had a few malfunctions. These were just in the first few mags. Once I got it nice and hot, the rifle was ready to roll and it has been going ever since. Accuracy of the rifle is better than I can shoot, at 25 yards it will cut little cluster groups with a dot sight. Out to 50 and 100 yards it was still on target. It is accurate enough with the dot to hunt or do varmint control. I did not put a magnified optic on it. I am sure that if I would have, it would have been more accurate. I was shooting from a standing position most of the time.

  This is a rifle that I would suggest to someone who wants quality at a good price. Or someone who just might not want a black rifle for whatever reason. If you live in one of those states where you can not have certain AR style rifles, the Foxtrot Mike Ranch Rifle might be just what you need. I plan on taking it on some of my hunting trips this year. It also stays close by in the house. It swings like that old 870 shotgun but with that AR rifle fire power.

AR Build: A young woman's perspective

A young woman’s perspective on building an AR15

  So I pitched the idea of building an AR to my daughter and writing something about it. She thought it would be fun. I am not sure if she was humoring me or not. But either way, here we are with an awesome AR15, that she built herself. A special thank you goes out to all the great companies that helped sponsor this build, you can read about their parts later in the story. 

From Zoe:

 Putting together my AR was much more interactive than I expected it to be. In a way it was simple, yet complex. Many little pieces combine together like a delicate puzzle, but also a straightforward process to get to the final outcome. There were many different steps to complete to bring it all together. One of the most tedious was putting all the pins into place! Those slippery little rascals!

  When putting the AR together, all of the parts fit perfectly. Between all the different parts, and parts kits, almost everything needed was there, even little tools for some of the steps! Everything was beginner friendly (although having my father assisting me helped a ton). I enjoyed the experience and the reward was incredibly worth the time put into it. Building the AR also helped me feel closer to my dad and the big parts of his life. As a young woman, knowing that there are places that put these part kits together brought me a sense of safety. I am able to build something to provide protection for myself. Plus I got to learn the intimate process of building it, in turn making me a safer firearms owner and a safer young woman.

  Shooting it was a lovely experience. The parts used were all relatively light in mass and resulted in a very lightweight gun. Having to hold it for long periods was undemanding. Shooting it was like a well polished machine. There was very little recoil when firing the rifle. It also functioned flawlessly and did not jam. One thing that I did struggle with was pulling back the charging handle. Which can be a common issue as a woman, since our upper body strength is usually lower than are male counterparts. Charging the firearm is easier than other guns I have shot because of the larger size charging handle. All of the parts worked as expected and I was very satisfied with the experience as a whole. 

  I am so grateful to have had this opportunity. It provided me with important skills, and knowledge of firearms, that I did not have before building this AR. To any young woman who feels she needs confidence and a sense of security, I would highly recommend learning the safety and process of building a firearm. There are things out there to make life a little safer, and I believe this is one of those. 

Stay safe out there ladies.

Sponsored parts used in Zoe's AR build:

This AR15 is built for .223/5.56, so everything listed below is for that particle caliber rifle.

  When it comes to AR parts, there are many. We were fortunate to have some great sponsors who supplied top notch parts for this build. A lot of these are colorful, literally, but they are all high quality parts. 

  First up is the backbone of any AR build, the lower receiver. Our friends over at Foxtrot Mike Products sent one of their stripped lowers. These are billet receivers with a slightly enlarged trigger guard and a semi built-in magazine well. The Magazine well is 3D machined to give it a super smooth transition when loading magazines into the rifle. The Foxtrot Mike lower has a bunch of small added features that make it a little nicer than your run of the mill lower receiver. One of those is the ability to run a ball detent on the safety. That little detail makes a safety selector work so much smoother. 

  Since that lower receiver needs parts to make it function, ArmaSpec sent a stainless Lower Parts Kit (LPK) and their Stealth Recoil Spring. ArmaSpec’s LPK is one of my favorites. It comes with an ambi safety selector that does 45 and 90 degree throws. We did not use the ambi selector in this build, but I did install it elsewhere. All the springs and detents in the LPK are well made and I have no doubt that they will give the rifle years of use. The Stealth Recoil spring, that ArmaSpec manufactures, is a wonderful piece of equipment. Its complete unit replaces the conventional AR buffer and spring. It is called “Stealth” because it reduces the “twang” noise sometimes heard in normal AR’s. The Stealth Recoil system smooths out the cycling of the firearm and also reduces recoil, which was noticeable by how soft this AR shoots.

  If you want a barrel and need it to look fancy, Faxon Firearms has you covered. Since Zoe wanted something “pretty”, we went looking. Faxon has a match grade 16” Gunner series barrel that happens to come in “Chameleon” PVD. This color option fades from pink to purple, to blue, and then to gold. A perfect option for someone wanting color. It also looks amazing under the Robin Egg blue color scheme. Faxon also sent a gas tube and a 0.625” gas block to round out the package. This barrel is not only super accurate, but it is fairly lightweight too.

  When you are building an AR of this quality, you do not want to skimp on the Bolt Carrier Group (BCG). After all, this is what makes the firearm function. Walker Defense sent us one of their Nickel Boron BCG’s. Nickel Boron provides enhanced reliability, easier cleaning, and better lubricity. Walker’s BCG is super slick, literally, and has all the top tier options someone would want. It uses a properly hardened 9310 bolt, has properly staked OCKS screws, is magnetic particle inspected, uses a hard chrome firing pin, and has a M16 carrier profile. Walker Defense’s products are also 100% made in the USA with US components. 

  To finish out the build, and add a whole lot of color, Timber Creek sent an Enforcer build kit. These are fairly lightweight kits which work well when you are worried about the final weight of the rifle. Zoe opted for the Robin Egg Blue cerakote color version. The Enforcer kit comes with a ton of parts for your build. In this case, the Robin Egg Blue parts we used were the 15” handguard, pistol grip, charging handle, safety selector, buffer tube, end plate, port door, extended mag release, forward assist, and takedown pins. We also used the supplied muzzle brake, but it only comes in basic black. Timber Creek's Enforcer kit also comes with a 0.750 gas block, which we didn't use due to using a 0.625 barrel. We also did not use the trigger guard since we used a billet lower that has the trigger guard built in. 

  I want to mention two things about the Enforcer kit. First up is the Ultra Light M-Lok handguard. These handguards, by themselves, are stupid lightweight. They also have holes for QD swivels. Making it easier to add a sling. There are also plenty of M-Lok slots along the whole rail for adding whatever you want. The second thing I want to mention is the oversized charging handle. This handle is significantly larger than most. Zoe mentioned it made charging the rifle easier due to its size. I had never thought of this, but because you can get a good grip on it, it works better for those that have a smaller stature. 

  As we all know, you need a way of aiming a rifle. Since this AR is not being used for distance shooting, She opted for a red dot. Why? Because it is lighter than a 1x prism sight. Primary Arms Optics sent us one of their MD-25's with the 2 MOA dot. The Primary Arms MD-25 is a great red dot. It has a large window size and is pretty lightweight. Battery life is really good thanks to it having Primary Arms’ Autolive function. The Autolive turns the dot off after a few minutes of non use, and then turns it back on when it gets moved. The MD-25 is a great option for a defensive rifle. 

  Now you may have noticed that we are missing a few parts. We supplied the stripped upper receiver, stock, and trigger. Most stripped uppers are very similar and fairly cheap, so I just purchased one. When it comes to stocks, there are a lot of personal preferences. We just opted for a Hogue AR stock. They lock up tight, have a good feel, and are inexpensive. If you noticed, the LPK was not one that included a trigger. I had a TriggerTech Duty Trigger laying around. It is the 3.5lb version. This trigger is a really good option for someone that doesn't shoot a lot. Yes, it feels really good, but with the 3.5lb pull weight, it works well for beginners and seasoned pros alike. 

  Now my daughter has her own AR15. The experience of helping her build her own rifle will not be forgotten anytime soon. She has a life saving tool that will give her a lifetime of protection and enjoyment. 

Jacob Grey AR trigger

Jacob Grey

Signature Drop in AR flat faced trigger

  I recently got an AR trigger from Jacob Grey Firearms. This is a flat faced 3.5 lb cassette style trigger. It came nicely packaged and also includes anti walk pins with it. Jacob Grey (JG) is known for their high end 1911 double stack 9mm handguns. When I got the trigger I had to figure out what rifle I was going to put it in. So I chose a Palmetto State lower with a Delton 16” upper. I had an LPVO on this rifle and was taking it to a class. This gave me the chance to run the trigger and get a good feel for it.

  After installing the Jacob Grey trigger I had a small hiccup with it. I followed the instructions that were in the box and I could not get the trigger to function right. I spent several hours working on trying to make it work. I reached out to a few friends, that I knew had the answers. I also called JG customer service and left a voicemail. After using my lifeline, I got the trigger running right. I didn’t realize there were two small set screws on the trigger that you have to run down until they meet the bottom of the receiver. Right after I figured this out the customer support team called me. There were two gentlemen on the phone and one was the head armorer. He gave me a run down and told me how to adjust the trigger after installing it. This was a refreshing relief to get a real person that knows what they are doing to call you back. The big aggravation I had was that there were no instructions on or in the box.

Image from Jacobgreyfirearms.com

  Installing the JG trigger was very straightforward, just yank out that old GI junk, and drop this one in. It came with anti walk pins to secure it. I did use some blue loctite on the screws, after I had one of the screws back out during a training class. So the loctite was definitely an after the fact thought. 

  When I took the rifle to the range I was really impressed with the very short trigger pull. There was no take up, the trigger break was crisp like glass. It was almost scary the first few rounds. After getting used to it, making double taps and triples was no problem. The travel of the trigger was just a out 1/16” of an inch. The reset was very noticeable and tactile. It was refreshing to be able to know where it broke and reset. I did a lot of single shots and held the trigger down and let up on it after the round had impacted. The reset was audible and very noticeable. 

  I took the rifle to a class and the JG trigger performed flawlessly. Granted I already had about 200 rounds on the trigger before this. The trigger was smooth, crisp, broke like glass, reset was wonderful. It almost felt like you could outrun the rifle with the trigger. It is not very often that I find something that I have to tell other people, “you just have to try this”. With the JG trigger I did. I asked several people to shoot it and tell me what they thought of it. Everyone was surprised at the crisp, light break and the reset. 

  So after having well over 1000 rounds on the Jacob Grey trigger it is staying in my go to rifle. The 3.5lb trigger pull is fantastic. I probably would not recommend this trigger to someone starting out just because of how light it is. I would recommend some range time doing drills before I ran it in a class or competition. After someone is used to this trigger, it would make a great all around do anything trigger. You can check the trigger out at Jacob Grey Firearms.

5 out 5 stars from John D. at OpticsPlanet.com

Alrighty, let me tell you about the Jacob Grey Drop in AR15 Trigger. If you're looking for a trigger that's super crisp and has a super short reset, then this trigger is the real deal, my friend.

I gotta say, I was a bit hesitant at first since I've tried out some other triggers that were supposed to be "crisp," but they just didn't cut it for me. But let me tell ya, the Jacob Grey Trigger definitely lives up to the hype.

First off, installation was a breeze. I'm no gunsmith, but I was able to install it without any issues. And once I got it on my AR, I was absolutely blown away by how smooth and crisp the trigger pull was. Seriously, it's like butter.

And let's not forget about that super short reset. It's insane. You barely have to move the trigger at all to get it to reset. And when it does, you're right back at that crisp trigger pull.

Now, let's talk about the price. For the money, you simply can't beat this trigger. I've seen other triggers out there that cost two or three times as much, but they don't even come close to the performance of the Jacob Grey. It's an absolute steal, in my opinion.

Overall, if you're in the market for a trigger that's crisp, smooth, and has a super short reset, then look no further than the Jacob Grey Drop in AR15 Trigger. It's a total game changer and worth every penny.

Black Talon Tactical AR trigger

  The AR market is saturated with aftermarket triggers. If you want to stand out from the big names, you need to do something better and different. Black Talon Tactical has done just that with their Single Stage Calibrated Adjustable Drop In trigger. Yes it has a long name, but it really does describe the Black Talon Trigger quite well. They shipped me out their Improved Finger Position (IFP) profile trigger to try out. For the $180 price tag, I was not disappointed. 

  Black Talon Tactical’s drop in trigger is different in many ways. These differences are all good in my opinion. One, it has an adjustable trigger pull weight from 2-5 pounds. Two, this particular version uses the Improved Finger Position (IFP) trigger shoe that I’ll describe later. Lastly, the Black Talon triggers also have zero take up, very minimal break travel, and a tiny bit of overtravel.  

  When Black Talon Tactical says the trigger pull weight is adjustable, it is even more than that. As mentioned, the trigger’s pull weight is adjustable from 2.0 pounds to 5.0 pounds. I am pretty sure they specify the decimal point because the trigger has a precision adjustment scale on it. Black Talon Tactical also states that the trigger is calibrated to within 1 ounce of the marked adjusted trigger pull weight. Plus, the trigger pull weights are repeatable on the scale. The only noticeable drawback to the IFP trigger is that it must be removed to adjust the pull weight. To adjust the pull weight, just use the supplied allen wrench to turn the screw to the setting you want, it’s that easy. For a small fee you can send Black Talon Tactical a stripped lower receiver and they will modify it so that the trigger can be adjusted without removing it. I did not send in a receiver, so I can not tell you anything about the modification. I will testify to the fact that the adjustment is repeatable. I adjusted the trigger a few times, and then set it back to a 2.5 lb pull. My trigger pull gauge reads 2.5 lbs pretty much every time I check the trigger’s pull weight. 

  While Black Talon Tactical makes these triggers in a standard curved and flat trigger shoe, they also have something different. This different shoe is called the Improved Finger Position (IFP) profile. Essentially the IFP shoe is a flat trigger until you get down toward the tip. Then the trigger has a little curved section that is angled toward the shooter's finger. This little section is about 5/16 inch long. What it does is allow for really precision trigger manipulation. Yes, you can get a really precise feel out of it. The straight portion of the trigger is then used for normal or fast shooting. I thought the IFP trigger shoe was great. It works just as described. When I want precision shots, I just move my finger down to the bottom. When I want to go fast, I just use the flat section of the trigger as normal. And this trigger is fast.

  Installation of the Black Talon trigger is pretty standard. Remove the safety and old trigger. Slide the Black Talon trigger into position. Slide in the supplied anti-walk pins. Tighten anti-walk pin screws. Install safety. Now for the important step: tighten the two rear screws that put upward pressure on the trigger housing. If these screws are not tightened properly, the trigger may not work correctly. I originally had the trigger in a polymer AR lower and had a few failure to fire’s. My best guess is that the polymer flexed enough to cause problems, since those two rear screws couldn’t get tight. When I installed it in a standard aluminum AR lower receiver, those problems stopped. It has over 500 rounds in the aluminum AR receiver and has run flawlessly for over 500 rounds. All the necessary allen wrenches are also included so there is no need to run around trying to find some.

  My favorite aspect of the Black Talon Tactical Single Stage Calibrated Adjustable Drop In trigger is the actual pull, or lack thereof. The actual amount of movement in the trigger, to fire the AR, is minimal. Black talon states 0.5 mm, which is 0.020“. I just know that when I tested it, it was less than 0.040”. The break on the Black Talon Tactical trigger is also fantastic. I wouldn’t say glass rod, even if it is close, but I will say it has a super short tactile feel to it. Overtravel is stated at 1.25mm, or 0.050” maximum. I don’t think the one I have is that long. I will mention that the overtravel feels shorter because it is not the normal free travel that most triggers have. Instead it feels kind of spongy, but it is so short that maybe I am just feeling the end of the total movement. Either way, the overtravel is not really even noticeable. The reset on the trigger is good and a little forceful. The reset is a little better than most drop-in triggers in this price range. Click here for a short video of the trigger movement. 

  I’ve put quite a few rounds through the Black Talon Tactical trigger. It is just so much fun to use. I have another trigger that feels a bunch like this one. The difference is that the Black Talon trigger is adjustable. Plus the IFP trigger shoe is unique in how you can go from fast to precision easily. When I was running a bunch of bill drills with the IFP trigger, I could get 0.10 second splits. 0.12 seconds were really common. If you want a really fast trigger, this may be one to look at. I probably wouldn’t recommend this trigger to a novice shooter. The break is just too short and quick in my opinion. But, the nice thing about this trigger is that you can set the pull weight up to 5 pounds, then as you get more proficient with it, you can turn the pull weight down. 

  If you can not tell, I became a big fan of Black Talon Tactical’s Single stage trigger. It really does everything an aftermarket single stage AR trigger should do. It has adjustable pull weight, a super short trigger pull, and a great trigger break. You also get the IFP trigger shoe for more precision shots. Go check out the Calibrated Adjustable Drop in Single Stage Trigger from Black Talon Tactical, it is worth a look.

Foxtrot Mike - Mike15 gen 2

200 rounds of ammunition was supplied by Target Barn for the review

  AR pistols have become very commonplace. Foxtrot Mike has designed their pistols and rifles to be a little different, but in a good way. They use an integrated bufferless recoil system in their Gen II AR’s. Foxtrot Mike sent me a 12.5 inch Mike-15 pistol with a few added in options. So let’s get into what advantages this Mike-15 has to offer.

  When you first look at the Mike-15 Gen II, it looks very AR15ish. That is because most of it is. The lower receiver is Foxtrot Mike’s standard AR15 billet lower. But installed in the lower is a rear picatinny mount that also doubles as the bolt stop. The upper receiver system is where the difference is. Yes, it uses a standard AR barrel assembly and is still direct impingement. Because the Mike-15 is a bufferless system, the bolt carrier is different. As is the self contained recoil system that is placed above the bolt carrier, not behind like in a standard AR. This does make the upper about a quarter inch taller than your standard AR. The Mike-15 also uses a forward charging handle. All of these work very well together.

  As mentioned, the Foxtrot Mike, Mike-15 lower receiver is billet. This means that it is machined from a solid block of aluminum, not from a forging. This allows Foxtrot Mike to add in some different features. One of those is an oversized built-in trigger guard. This guard also has a slot in the bottom of it. I don’t know if it is for weight savings, or if it is for something else, but it looks nice. Foxtrot Mike also machines in a radiused 3 dimensional magazine well. This is a pretty nice feature to aid in reloading the rifle/pistol, even if you can see a few light machine marks in the magwell. Some other advanced features are: a screw in bolt catch pin, threaded and set screwed spring for the rear takedown pin, a ball detent for the safety with a set screw to hold it in (normal style spring and detent work also), and a screw for tightening the upper to lower fit. This Mike-15 also came with an upgraded Hiperfire trigger and an ambidextrous safety selector. The safety selector came as a 90 degree throw, but can be switched to a 45 degree, which I did as I like short throw safety levers. The optional Hiperfire Eclipse trigger is fantastic and has a pull weight of 2.5 pounds. The Hiperfire is not listed as an option on the website, but contact them and they will let you know how much extra it adds to the price. I also have a stripped Mike-15 lower for a different project, this is partly why I know about all those extras. I should also mention that the rear picatinny rail installs into the buffer tube threads and has the recoil bumper attached in it. It also has a QD slot at the bottom of the rail, so if a brace is not attached, a sling can be.

  The Upper receiver of the Foxtrot Mike is really where the huge differences are in this pistol, and their rifles. To start with, the upper receiver contains the recoil system. It is housed above the bolt. This recoil system consists of a dual spring and guide rod. The guide rod also goes through the top part of the bolt carrier. This allows the bolt carrier to push against the recoil system. The Mike-15 then uses a standard AR bolt assembly, but not a standard carrier. Because of this system, the receiver is about a ¼ inch taller than a normal AR’s receiver. The extra ¼ inch can make optics sit a little higher. This doesn’t cause any problems on the pistol version, but on a rifle, your optic may need a slightly lower mount. Foxtrot’s upper receiver does not have a forward assist, but does have a shell deflector. The Mike-15 gen II still uses a gas impingement system, so no differences over a standard AR in that respect. Except that the gas block is pinned, not set screwed or clamped. Foxtrot Mike then installs a 4150 barrel. This one is 12.5 inches with a mid length gas system. Because of the higher receiver height, a M-Lok rail that matches the height of the upper is installed. This handguard measures 11.75 inches, so it comes up flush with the muzzle brake. Depending on the rifle or pistol you order, the handguard length will vary. Lastly, Foxtrot Mike put a nice little 4 port compensator on this pistol. The comp works better than I was expecting it to.

  Operation of the Mike-15 gen II is a little different then a standard AR15. Instead of using a rear charging handle, Foxtrot Mike designed a forward charging handle that is in the upper part of the handguard. The charging handle is basically in the part of the handguard that is taller, so it doesn’t affect the M-Lok slots or get in the way. You can set this charging handle up to be either right or left charging. The charging handle DOES NOT reciprocate. However, it can be angled either slightly up, or slightly down, depending on how you have it configured. It comes curved up on the left side of the firearm. A folding lever is also available from Foxtrot Mike. The folding lever folds out of the way against the upper, for a more streamlined charging handle.

  Maintenance on the Mike-15 gen II is also a little different. Because of the self contained recoil system, you can not just pull the bolt out like a standard AR. On the top rear of the upper, there is a little square plug with a hole in it, located where the charging handle on a regular AR would be. One must use a small punch, or something, and push down the recoil spring assembly. Then slide the plug down. Watch out for lift off of that spring, as it can go flying. Then just pull the recoil spring assembly out, tip the gun back, and the bolt carrier should slide right out. All the other maintenance stuff is pretty similar to what a standard AR is.

  The Mike-15 pistols come in a variety of options. Some of those are barrel length and different colors. These pistols can be had in the picatinny rail version. Meaning they only have the pic rail on the rear of the receiver. Or you can get them with a folding SBA3 brace. I'd opt for the folder. The Mike-15 12.5 inch they sent me had an A3 Tactical folding brace with an A3 Steady Brace. These braces are top tier and work great. Plus they are super lightweight. If you want one of these as an add-on to your Mike-15, just ask Foxtrot Mike Products to see what they can do for you. The A3 brace folds to the left side of the Mike-15. Because the Mike-15 uses the forward charging handle, the brace does not get in the way of manipulating the firearm. Yes, of course the Mike-15 will fire while the brace is folded because of the self contained recoil system. 

  The Mike-15 that they sent was pretty solid. I’ve run a bunch of bill drills with it, along with other stuff. Target Barn supplied some 5.56 to help with the review: 100rds of Winchester 5.56 55gr M193 and 100rds of PMC 5.56 55gr. The Mike-15 currently has over 500 rounds through it. I did run into a problem with the recoil system after around 150 rounds. The springs were binding up and wouldn’t allow the bolt to go rearward all the way. I contacted Foxtrot Mike and they sent the “new” style buffer springs and guide rod. I literally had them the next day! Somehow the “old” style guide rod had been installed in this Mike-15. It has run flat out since with zero malfunctions since the initial problem. During my conversation with Foxtrot Mike, they also told me that they have a buffer tube spacer that plugs the buffer tube in case you want to run the Gen II uppers on a standard AR. They sent me one, so I tried it. The Gen II Mike-15 upper ran fine on a standard AR lower with that buffer tube spacer. One thing to mention is that the Mike-15 uses a different manual of arms, kind of. Because of the forward charging handle, one needs to readjust a little. Is this a bad thing? I don’t think so, but I thought it needed mentioning. When it comes to that manual of arms, the Mike-15 also seems to take a little more muscle power to manually cycle the bolt. Probably a non-issue for most. Watch a short clip of how it runs HERE.

  There are a few aspects of the Mike-15 that I really like. The first is the folding brace. I really liked this addition. One, because it folds and makes the Mike-15 really compact. Two, because it has M-lok slots in the arm. Having M-lok allows me to install a QD socket so I can run a sling easily. The next aspect I like is the weight. It weighs 5.6 pounds on my scale, and that is with the Lucid E7 blue-dot optic and the brace. When it comes to performance, the Mike-15 can hold its own. Being only a 12.5 inch barrel, I do shoot it slightly slower than a 16 inch barreled AR, but it is still fast. The Hiperfire trigger helps with the speed also. It is a very nice trigger upgrade. Lastly, I really like the self contained buffer system as it makes the Mike-15 pistol something you can shoot with the brace folded. I’d say the performance of the Mike-15 is above par for the price you pay.

  Foxtrot Mike designs their products for the everyday user. You get a high quality product for not a ton of cash. The Mike-15 Gen II pistols start at $699 MSRP and work their way up from there, depending on options of course. If you are looking for a truly foldable ARish pistol or rifle, the quality you get from Foxtrot Mike is top notch. You can check them out over at fm-products.com.

5 out 5 stars at Brownells - yes it’s for the rifle version, but it is still close   

One of my favorites

I purchased the 16" as well as the 11.5" pistol version. I shot the 16" primarily and was able to zero at 100y and hit targets at 500y without issue. A bit more fine tuning with my scope could yield a bit more in its capability. Some things to note about the rifle: I had some issues with the first round in a magazine going into battery and having light primer strikes that were rectified through break-in. After a couple magazines, I had zero errors. The biggest issue I had was getting proper eye level with my sight. Be aware the Zhukov stock and the folding, mounting system sits 0.25" lower than a standard AR. You may have to buy the $15 0.25 Magpul AK Riser to get the proper eye line. I paired my 30mm LVPO with a low mount, cantilever scope mount. In all, it only cost an additional $50, but I wish there were a way to have the stock sit at the same level as a buffer tube would. This is information I wish had been noted in reviews/videos before purchasing the rifle. Am I happy with my FM-15?Yes, it's probably my favorite AR long gun. Would the sight-line information have changed my decision to buy? Maybe, but ultimately I'm happy to own such a unique rifle. Time will tell if I enjoy the pistol length version as much as the 16".Though, I do hope Foxtrot Mike develops a 300BLK, short barreled upper of the same style.

Primary Weapon Systems MK116 Pro Upper

 When it comes to AR upper receivers, there are a ton to choose from. You can get dirt cheap, or super hi-end. There’s also different ways for the firearm to cycle those upper receivers. One of those is the long stroke gas piston. Which leads us to Primary Weapon Systems (PWS for short). Primary Weapon System has been making long stroke gas piston AR uppers for some time, as well as complete rifles. PWS is well known for their long stroke gas piston AR’s and upper receivers.

  Primary Weapon Systems sent me one of their MK116 Pro Upper receivers. Which version they sent isn’t as important as how the upper operates. As all of the PWS uppers use the long stroke gas piston for operation. The long stroke gas piston operates differently than your standard AR’s direct impingement system. Instead of using the gas to cycle the Bolt Carrier rearward, the PWS long stroke gas piston uses a piston that is, essentially, directly hooked to the BCG through the piston rod. When gas comes into the gas block, it directly pushes on the piston to cycle the action. This gives a few advantages over the normal direct impingement system. For one, the gun runs cleaner because all the gas isn’t being directed directly into the action. It also allows the action to run cooler, since the hot gas isn’t being directly blown into the action. A big plus if you are running an upper on a full auto gun. Lastly, the action can tend to run smoother because all the operating parts are fixed together. There are also a few downsides to a long stroke piston upper. They can weigh a little more. The PWS upper is only a few ounces heavier than my comparable DI upper, so it’s not a lot of extra weight. The only other notable thing is that it comes apart differently than a DI upper. Not a big deal at all, just different.

  The PWS MK116 Pro upper has a lot of great features. First off, I’ll mention that I received the 16” barreled version. This is important to note because it uses a mid length gas system for the piston. It also has a 15” M-Lok handguard. The handguard is a little different then what most people are used to. This is because it is missing a small chunk of the top picatinny rail, or basically one lug of the rail. This lug is missing so that you can easily adjust the 3 position gas block. The MK116 also runs a slick side upper, so no forward assist. There is a small shell deflector on it to keep the ejected brass from hitting you, but it will hit your camera man in the face. This particular upper came with an A2 birdcage. If you want flash suppression, the A2 birdcage works very well. Lastly, the PWS MK116 comes with a Radian Raptor charging handle. I really like the Raptor charginging handles, PWS made a good choice in using them. 

Staking on Carrier bolts is different due to long stroke piston setup

  PWS gave the long stroke gas piston uppers, and firearms, a 3 position gas block. As mentioned earlier, this is easily adjusted through the handguard. One can even use the tip of a bullet to adjust it. The 3 positions are labeled 1,2,3, and “X”. All 3 positions have a detent and click to them. The X position is for disassembly and cleaning, it’s not a click adjustment. Position 1 is for unsuppressed use, or normal everyday use for those without a suppressor. Position 2 is for suppressed light loads or low back pressure (flow through) suppressors. Position 3 is for suppressed heavier loads or higher back pressure suppressors. I did try out all 3 positions. Position 1 works exactly as advertised. Position 2 would eject rounds without a suppressor, most of the time, Position 3 would not cycle without a suppressor. With my 556 suppressor, position 3 was spot on. Positions 1 and 2 had a bit of force behind the ejection pattern. I really like how PWS gives you a simple, yet effective, way to adjust the upper for suppressed and unsuppressed use. Through all my testing on the PWS upper, I had zero malfunctions, not counting the ones I caused by using the wrong gas position (I had to test them). I also used a variety of ammunition types and brands for testing, both suppressed and unsuppressed.

  Being that the Primary Weapon Systems MK116 was just a complete upper receiver, I needed something worthy of mounting it on. I ended up using an Aero Precision lower. This lower has a few options that make it a great companion to the PWS upper. The lower has a Blackout Defense Zero trigger installed in it, a VZ stipple grip, and an ambi safety selector. The trigger is what really makes such a great combo with the PWS long stroke piston. You can shoot this rifle super fast if you want to. Also, I needed to have some way to aim the rifle. I ended up using a 1x prism sight. Well, I did have a 1-6x on it at first, but I took it off in favor of the prism. The last thing I did to enhance the PWS upper was to install some NILE grip panels and a sling. The NILE panels use a M-Lok attachment, so they mounted up super easy to the PWS M-Lok rail. I had to use a M-Lok QD attachment for the sling. This particular PWS upper doesn’t have QD mounting points built into the handguard, that’s not a big deal for me, but it would be nice. I was really happy with how the PWS upper worked in conjunction with my lower receiver. The fit to the lower receiver was a bit tighter than what I would call “normal”, but not tight enough that it was hard to install on the lower. The PWS upper, when mated to my lower, made a really nice rifle.

  Anyone looking for a great way to upgrade an AR rifle, needs to look into the Primary Weapon Systems long stroke gas piston uppers. The PWS system works very well. The action is super smooth. The piston system is robust and will keep your rifle cleaner than the original gas system does. If you are using a suppressor, it also keeps the blowback gasses out of your face. So if you are searching for a top tier upper receiver, do yourself a favor and go check out what Primary Weapon Systems has to offer.

TriggerTech AR Duty trigger

  When it comes to aftermarket AR triggers, there are numerous options. One of the categories some of these fall under are “Duty Grade” or “Enhanced Duty Grade”. I tend to lump everything in these categories into the “Enhanced Duty Grade” except the standard mil-spec trigger. That leads me to Triggertech coming out with their version of a Duty Trigger. Triggertech was kind enough to send me an AR Duty Trigger at the same time they sent the AR Diamond trigger.

  Since this is a duty trigger, I opted for the curved shoe version. As you may know from previous reviews, I like a curved trigger. Triggertech does make the Duty version with their signature straight shoe also. Triggertech’s curved shoe is pretty close to the same width as a mil-spec trigger. But it feels narrower due to the ribs on the face of it. Because of this, the face is more radiused than the mil-spec trigger. However, the curve on the shoe seems to be the same as a mil-spec trigger. I really like the physical feel of the Triggertech curved shoe. 

  This Duty trigger has a few options available. I already discussed the shoe options, so those are taken care of. First, the Triggertech Duty comes in either a fixed 3.5 lb pull weight, or a 5.5 lb version. I opted for the 3.5 lb version as I like lighter pull weights, even in a duty trigger. Both of those pull weight options are also available in a single stage or two stage version. I opted for the single stage, which is just that, one pull and break. The two stage will have some light take-up before you hit the wall of the trigger pull and break. It’s really personal preference as to which one you go with.

  The Triggertech Duty trigger comes as a cartridge style, drop in unit. This makes installation a snap. Triggertech used a different material for the Duty’s housing. They are using a EZAC diecast zinc. Here’s what I found on EZAC: “EZAC is a hot-chamber zinc die casting alloy with superior creep resistance, high yield strength, and high hardness.” So basically the housing should last a long, long time. The parts inside, that really matter, are made from 440C stainless. The trigger shoe is also PVD coated black. Drop-in triggers are my choice for trigger installs and not all “Duty” triggers are this way.

  Since this Duty trigger is made by Triggertech, it inherits some of the technology from its higher end siblings. This means that you get the benefit of having their roller bearing between the trigger and sear. Big deal you say? Yes it is, because it removes the friction portion of a trigger pull. Rollers always beat friction, at least in my world. This makes the trigger have essentially no take up. At least on the single stage version. If you want to know more about Triggertech’s technology, you can check out their How-It-Works page. I think the only tech it doesn’t have is the CLKR adjustment,  but that’s because it’s a fixed pull weight.

  I will say, the Triggertech Duty has one of the best “duty” trigger pulls I have felt. There is no take up, just a crisp 0.050” break, with some overtravel. Here is where the trigger gets weird. If you dry fire the trigger, it has about 0.025” of overtravel. But when you cycle the action, after pulling the trigger and holding it (also during live fire), the trigger moves rearward another 0.050”, for a total overtravel of around 0.075”. This gives the Triggertech Duty trigger a 0.125” reset, or an ⅛”. This isn’t bad for a duty trigger, but it does make the trigger a little slower to shoot. Not in a bad way, just different. The clean break definitely makes up for the reset. Speaking of reset, it's pretty good. Not as strong as a mil-spec trigger, but better than the Triggertech Diamond line, at least in reset feel.

  I ended up sticking the Triggertech Duty trigger in my Kaiser Blackbird. It was a great addition to the lightweight build. The trigger shoots very well in it. Double taps are fairly easy and quick for a duty style trigger. Bill Drills (6 shots) are a little slower due to the reset not being as short as non-duty triggers, but still manageable. Overall, the Duty trigger is still a great trigger in this category of AR triggers.

  As I mentioned, the Triggertech AR Duty trigger is one of the best I have felt. I don’t think you can go wrong choosing this trigger, especially when you find out the MSRP is only $130 bucks. So if you want a good inexpensive trigger, or if you need an actual “Duty” grade trigger, go check out Triggertech’s version of a Duty trigger.

TriggerTech AR Diamond single stage trigger

  I am someone that is always looking for the newest and best AR trigger. I have found some that are pretty fantastic. Which leads me to the Triggertech AR Diamond Single stage trigger. The Diamond is Triggertech’s top of the line model and it shows. They were gracious enough to send me one for review, and I am glad they did.

  For this particular review, I opted for the straight trigger shoe. Triggertech also has a curved option in the Diamond line, if that is your pleasure. I am known to like a curved trigger, but for a hi-performance trigger, I can get behind the straight options. The shoe is definitely straight and flat, but also has a tiny hook/knob at the foot. There are no sharp edges anywhere on the trigger,  even if it looks like there would be. The trigger felt great to me, which surprised me since it has no texture on it and is super smooth. Part of that feel is in the trigger operation, but more on that later. Triggertech also puts a “TT” at the very top of the trigger, where it pivots. A nice touch to say whose trigger it is.

  Let’s get into what makes the Triggertech Diamond single stage work so well. The most notable aspect to Triggertech triggers is their use of a roller between the sear and the trigger. They call this Frictionless release technology (FRT). This roller allows the trigger to not have any friction in the actual trigger pull. Most every other trigger on the market uses the friction between the sear and the trigger. You can definitely feel the difference because of the FRT, especially if you compare it to a standard friction trigger. They also use their TRK system to give you the shortest trigger pull possible. If you are curious about their other tech, check out their How-It-Works page.  

  Since the Diamond trigger is at the top of Triggertech’s lineup, it is adjustable. Triggertech states an adjustable pull from 1.5 lbs to 4.0 lbs. I can attest to these values, as I adjusted it all the way down and back up. To adjust the trigger pull weight, there is a set screw at the rear of the trigger housing. Turn clockwise to increase pull weight, and counterclockwise to decrease pull weight. This set screw also uses Triggertech’s Clicker technology. Essentially the set screw clicks every 2 oz of pull weight. The Clicker adjustment makes adjusting the pull weight super easy. I have mine set at 2 lbs and love it. The Diamond came set at 2.5 lbs on my trigger pull scale. It is definitely one of the easier triggers to adjust, due to that single adjustment screw.

  For those wondering, the Triggertech Diamond is a drop in style trigger. This cartridge style makes installation easy. The cartridge is made from 7075 aluminum. Does it need to be this higher grade of aluminum? Probably not, but it does show quality. If you are worried about it wearing out, don’t. Even if it did, it’s covered by the lifetime warranty. One thing I wish that Triggertech included were anti-walk pins. Yes I can get them inexpensively, but in a top tier trigger, I think they should be included. I have criticized other companies for the same thing, even if it is kind of nitpicking.

  Now for the really good stuff. The Triggertech Diamond has essentially zero take up or creep. Yes, I can’t perceive any, or measure it with the tools I have. There is also zero perceived over travel. You simply put your finger on the trigger and apply pressure. Then the trigger breaks with one of the cleanest breaks I have felt on an AR trigger. When I measured the total movement of the trigger, it measured at 0.050”. This was at the very bottom of the trigger shoe, so it is less as you move your finger up the trigger shoe. The trigger pull on the Triggertech Diamond is fantastic. Now comes my only complaint, and it’s minor. I would like the reset to be stronger. Triggertech calls it “tactile mid force”, which I think is a fair explanation. The reset works fine, even when shooting really fast, I just want a tactile high force reset. This trigger can be shot super fast if that’s what you want. If you like single stage triggers in a precision gun, it would do a fantastic job there too.

  The Triggertech Diamond has impressed everyone that I let use it, even me. The Diamond is just that good. I did run it in a local match where it performed well. There were some rapid fire targets, and some small precise targets. The Diamond made it easy to do both and transition between them. When the sight was on target, I just touched the trigger and made decent hits. I attribute this to the consistent pull weight and lack of any trigger take up. The Triggertech Diamond is now in my top 2 triggers for an AR. The Diamond is a better all around trigger than my other top pick, which is more a speed trigger. The Diamond single stage can do everything an AR trigger should do, and it does it extremely well.

  If you are looking for a great AR trigger, do not skip over looking into Triggertech. The Diamond AR single stage trigger does everything one could ask for. It works for precision shooting, as well as ultra fast shooting. I definitely place it in the best of the best category. If you want a top quality AR trigger, check out the AR Diamond from Triggertech.

5 out of 5 stars from Tuomas K. at TriggerTech 

I have been solely using Triggertech triggers on all my platforms since the IPSC World Shoot Rifle 2019. I have tried a lot of other triggers throughout the years and can happily say that I found the best in Triggertech Triggers. I run them on my AR-platforms, PCC:s and my PRS rigs. The Diamond triggers are beautiful and I love the action and the clean break in them.

Even though I love my red Diamonds for the AR-platforms, the new Single Stage Diamond Trigger will be my go-to trigger for the future. Got the opportunity to test this trigger out and I basically love It!

Superfast, short distinct reset and breaks like glass, every time!

Kaiser X-7 Blackbird receiver set

  When you think about lightweight AR’s, you usually don’t think of composite hybrids. Kaiser US is here to change that, and in a big way. Kaiser has plenty of experience in the hybrid AR market with great product success. Recently they introduced a new Titanium-Graphite composite AR15 receiver set called the X-7 Blackbird. The name pays tribute to the SR-71 Blackbird spy plane, a composite plane that was way ahead of it’s time, thus similar to the X-7 Blackbird receiver set. After having Mike, from Kaiser, on the podcast, he offered to send me one of these hot new Blackbird receiver sets for review.

  Let’s talk a little about this Ti-Graphite composite. There are a lot of misnomers about composite, or plastic, receivers. Even though some of these are true, they do not apply to the Kaiser X-7 Blackbird, or any of Kaiser’s other receivers. This is because Kaiser engineered the composite receiver, so it is not just your everyday “polymer” like the others. It has more material in certain places to help with strength. But Kaiser doesn’t stop there. They wanted it to be stronger than the standard aluminum AR15 receivers. So they put titanium and anodized aluminum inserts into the places needing strength. For instance, some of these places are the threads for the buffer tube and the barrel nut threads. The Blackbird’s Ti-Graphite composite also adds in some more strength, simply because the titanium and graphite are molded into the composite. Another huge advantage to the Ti-Graphite composite is its lubricity and wear resistance. Essentially, it is so smooth that very little to no lubrication is needed. I still put some oil on the BCG, but it cycled smoothly without it. So what does this Ti-Graphite composite get you? It yields a super strong upper/lower receiver set that weighs in at 9 ounces stripped. For comparison, a standard stripped, forged AR15 lower receiver, without an upper, weighs 8.8 ounces.

   Besides the Blackbird being a super lightweight receiver set, it also has some other enhancements. Up first is its textured magwell. Not only is it textured on the side, but the front as well. This texture consists of raised rectangles. For those of us that grab the magwell with your support hand, this gives you a good, no slip, grip on the Blackbird. The magwell is also beveled to help get those magazines changed quickly. Next is the fit between the upper and lower receiver. It’s tight! I have never had a matched receiver set fit like this before, in a good way. I can push the receiver pins out, hold the upper, and shake it vigorously before the two halves come apart. If you are using the Blackbird for a precision style rifle build, this fitment would be perfect and would definitely help in the accuracy department.

  With the X-7 Blackbird being engineered differently, it has a few slight differences. All of them are good, just different. First, since the lower receiver is slightly wider than a standard aluminum one, at least in some spots, it can’t use standard anti-walk pins to hold the trigger in place. Standard trigger pins will work, but there is no reason to use them. Kaiser gives you their proprietary V2 anti-walk trigger pins, as well as the allen wrenches to install them. These V2 pins work for any trigger you wish to install into the Blackbird lower. It pretty much accepts any mil-spec or drop in AR trigger. The X-7 Blackbird also uses a proprietary port door on the upper receiver. As with the trigger pins, the lightweight port door assembly is also included. Most standard and ambi safeties will work with the Blackbird. I installed a Timber Creek ambi safety and it works well. Because the Blackbird is about weight, Kaiser also includes a skeletonized titanium grip screw for mounting your favorite grip. I went with the old A2 style grip, because it is one of the lighter weight grips around. The Blackbird upper receiver also does not have a forward assist. My guess is to save weight, since the forward assist isn’t always needed. The last two differences have to do with assembling the lower and upper. Instead of being able to put the rear takedown pin spring in normal, it now goes under the pistol grip, similar to the safety detent. I have zero problems with this, it's just different enough to mention. When installing a barrel and handguard onto the Blackbird, Kaiser recommends the use of a “reaction rod”. This prevents the upper receiver from being over torqued and damaged. They also only recommend 30 ft lbs of torque on the barrel nut as to not cause any unseen damage to the receiver.

  A little bit about the build with the X-7 Blackbird receiver set, is in order. I wanted to try and make this build pretty light, since the Blackbird is so light to begin with. I basically took an assembled AR pistol and took it apart, that way I could use the lightweight parts on the Blackbird. These consisted of a Faxon Lightweight 10.5” pencil barrel, a Walker Defense Titanium BCG, a Dark Hour Defense Magnesium handguard, and some other miscellaneous parts. What this gave me was an AR pistol that weighed 4.2 lbs without an optic. That is with parts that one can buy everyday, no custom special parts here. If you were to put a small lightweight red dot on it, it wouldn’t weigh much more. I did install a larger red dot, a finger stop, and a light. This only brought the weight up to 5.2 pounds, which is respectable with a light. It is possible to get the Blackbird to below 4 lbs without sights, I just haven’t tried to do it yet. One could put a shorter handguard and some titanium small parts to help reduce the weight even more. I am happy with how this build turned out. When you pick it up next to my decked out 11.5” SBR, it feels like it weighs nothing.

  How does it shoot? “Fantastic” would be the first word to come out of my mouth. The Ti-Graphite composite makes it so smooth. There really is barely any recoil, partly due to the Ti BCG and adjustable gas block. But It’s smoother feeling than when the same parts were in a standard aluminum receiver set. Double taps are super easy and quick to make. Essentially, this lightweight Blackbird receiver set makes an awesome place to start your lightweight AR build. I’m sure full Blackbird rifles will be available soon if building isn’t your thing.

  In the end, if you are looking at a lightweight AR15 receiver set, the Kaiser Blackbird can help you out. This Ti-Graphite matched upper/lower receiver set is one of the strongest and lightest ones around. The Blackbird is way lighter than its nearest, more expensive competitor. Don’t be scared by those who say “plastic” will break, they haven’t used the Blackbird and they probably haven’t ever heard of Kaiser US either. So, if you want one of the lightest AR’s around, start with the Kaiser X-7 Blackbird receiver set and don’t look back. You’ll be getting a quality product that will perform above your expectations.

AR Gold trigger

  Some time ago I was asked if I had ever used an AR Gold trigger. My answer was “no”, but I had heard they are pretty good. That led me to ask American Trigger Corporation if they would send one out for a full review. As one can guess, here I am with a full review of the Adjustable, curved, AR Gold trigger.

  When the AR Gold trigger showed up, I eagerly installed it into a lower receiver. The AR Gold comes in a nicely packaged box with some stickers and such. The packaging itself makes the trigger look like a finely tuned race car, which it kind of is. Since the AR Gold is a cartridge style AR-15 trigger, installation is very straightforward. 

  As mentioned, I opted for the adjustable version. Yes, a non-adjustable one is also available, its pull weight is set at 3.5 lbs. The adjustable one is also set at the factory to 3.5 lbs. I set mine a little lighter, down to 2.5 lbs. To adjust the AR Gold trigger, there are 2 set screws at the back of the trigger housing. Use the top screw. Clockwise will increase the sear tension, thus increasing the break weight of the trigger. Of course, turning the screw counter-clockwise will decrease the sear tension, lightening the trigger break. From ATC Gold’s website - “As you reduce the amount of spring tension on the sear, you WILL reach a point that the gun will not cock reliably when live firing – though it may still cock dry firing. On most AR’s this will occur somewhere between 3 and 2 lbs.” So go slowly with your adjustments. From my understanding, there is really no need to even go near the bottom screw on the trigger housing. I had no problems adjusting the AR gold trigger down to a measured 2.5 lbs, everything still safely checked out as normal. Individual results for the trigger adjustments may vary. ATC also designed this trigger from the ground up. It is not just a modified GI trigger in a drop-in cage. Which is really noticeable if you compare them side by side. 

  The trigger pull on the AR Gold is really good, but it may not be what you are used to. It is more like a really good 1911 pistol trigger pull. ATC has a good explanation on their website, but essentially it says “AR Gold is a single-stage with a slight bit of very light (8 oz.) of take up.” After the take up, you then hit the “wall,” this is where the actual pull weight is. Apply pressure and the trigger breaks super crisply. This is by far one of the crispest trigger pulls I have felt. When I measured it, at the bottom of the trigger shoe, the break only moved the trigger around 0.050”. So up higher on the trigger, the pull length is actually shorter. After the break, there is some slight over travel. Not a bunch, most people might not even notice it. Then there is the reset. The reset is short, essentially the same as the break of the trigger. But, the reset is not very positive. It didn’t seem to matter if the trigger was set to the factory 3.5 lbs, or the 2.5 lbs I set it at. I would have liked to see a more positive reset, but I could still shoot this trigger very fast. All kinds of “super fast” professional shooters use this trigger, so it’s not like the reset is slow.

  I chose the AR Gold with a curved trigger shoe. Why? Because I like the consistency that a curved trigger gives me. ATC also offers a flat style trigger shoe. I think the flat style looks better, but I’m about functionality. The AR Gold trigger shoe is pretty narrow. It doesn’t affect anything, it’s just notable compared to a GI trigger. The curve of the trigger feels very much like the curve of a GI trigger, at least to me. The trigger, as a whole, feels like an expensive watch. It functions superbly, but also looks elegant. 

  The AR Gold trigger could be used on just about any style of AR rifle. It is fast, has a great break, and is adjustable. So if you are just into backyard plinking, or full blown competition, the AR Gold might be something to look into. I’m probably going to stick it in a AR varmint rifle build, but what you do with one is really up to you. American Trigger Corporation did a great job making a 1911 style trigger for your AR. If you are into finely tuned race cars, or triggers that are similar, then you need to check out the AR Gold trigger.

Pricey yes, but a great trigger. A clean sheet design. Not a reworked set of standard parts but a whole new way of thinking. Pulls very light and crisp. Yet punches deep pits into the primers. Can't comment on long term results until much more "testing" is done. But so far, perfect reliability and function. Just wish they were a bit cheaper. Then they would be a 5 star rating!

Expo Arms Patrol Series AR Upper

  Expo Arms has recently gotten into the AR-15 upper receiver market. They have a few options for pistols, SBR’s, and standard AR configurations. This particular upper is their Patrol series with a 16” barrel and A2 flash hider. If you didn’t know, Expo Arms is the in-house brand for Primary Arms and is sold exclusively through them.

  The Expo Arms Patrol Series is an everyday use AR-15 barrelled upper receiver. These do not come with a bolt carrier group (BCG) or charging handle. However when you order the upper, Primary Arms gives some drop down menus with discounted add ons, such as a BCG. The Patrol Series comes with a bunch of good specs: A 5.56 chamber, 1:7 twist nitrided 4150 cmv barrel, mid-length gas system, A2 flash hider, T-marked upper receiver, and a 15” M-Lok handguard.

  Barrels are an important part of any AR system. On 16” barrels, like this one, I like mid-length gas systems. They are smoother feeling and put less wear on components then a carbine length gas system. Being that the barrel is also salt bath nitrided, it will have a good lifespan and keep corrosion away. Expo Arms uses a SOCOM profile on the barrel. I like the profile as it gives strength and consistency without being heavy. Of course the muzzle is threaded and comes with an A2 flash hider installed. The barrel consistently shoots under 1 MOA for me with 69 grain match rounds. 

  Expo Arms uses their own T-marked upper receiver. This is a standard forged version made from 7075-T6 aluminum. It has a round style forward assist and a standard mil-spec port door. The whole upper is nicely machined and anodized. 

  To cover the barrel, and give you something to hold onto, is the 15” M-Lok handguard. This is a very nice, useful, no frills handguard. It runs a full top rail that is not sharp. The sharp parts of the rail have been deburred slightly. Along the other portions of the handguard are M-Lok slots. These M-Lok slots are every 45 degrees around the handguard, not just the standard of every 90. It’s a clamp on style handguard, but also has some anti-rotation tabs to keep it from rotating. I’ve never had a problem with these style handguards rotating on me, but the tabs are a nice addition. I really liked the Expo Arms handguard, I’d even consider it as a stand alone item. 

  If you’re looking for a good quality AR upper, the Expo Arms Patrol series might just be it. It has a lot of nice features for the price. In fact, I am still amazed at the 0.75” group I shot with it. Definitely go check out the Expo Arms series of stuff over at Primary Arms.

Dark Hour Defense MAGNESIUM DARKLITE handguard

  As one may have heard, I was building out a lightweight AR pistol and was in need of a lightweight handguard. Along comes Dark Hour Defense with their Magnesium Darklite M-Lok handguard. If you haven’t heard of Dark Hour Defense, they are a sister company of V Seven Weapon Systems. Dark Hour Defense is more of the “not as fancy” line, but still using the same technology and quality of V Seven. This makes the Dark Hour products more cost effective for the end user. 

  I decided on the Darklite handguard in the 9.2” length. I chose this length because I was using a 10.5” pencil barrel. Essentially, I didn’t want the handguard to extend over the muzzle, but also wanted it to cover the gas block. The 9.2” Darklite turned out to be just perfect. Dark Hour also has a 7.1” as well as sizes out to 18”. Outside diameter on them is 1.5”s wide and 1.97”s tall. The 1.97” height is due to the full length top rail. Inside diameter is 1.3” wide and 1.55” tall. 

  The Darklite handguard is super light! The 9.2” comes in weighing 4.23 ounces, on my scale, without any hardware. The barrel nut adds in another 1.13 ounces. Add in some mounting screws and the total weight is 5.64 ounces. I will mention that the weight listings on the Dark Hour Defense website are really close to the actual weight I measured. To get this lightweight handguard, Dark Hour uses an aluminum magnesium alloy that is 30% lighter than standard 6061 aluminum. It appears to be just as strong, if not stronger. Remember, this handguard also has a full top picatinny rail. The barrel nut is made from 7068 aluminum, which is harder and stronger than 7075 aluminum, but weighs less than steel by a good margin. All one needs to really know is that these are super light and strong.

  The Darklite handguard is pretty normal in other aspects except one. As noted before, it is running a full top picatinny rail. The M-Lok slots are at 3,6, & 9 o’clock. As of now, it is only available with M-Lok, because that’s the standard in my opinion. Instead of anodizing, Dark Hour uses a plasma deposition coating that gives a “tough ceramic-like coating with superior wear resistance compared to anodizing.” I’ll agree, this E-Cote finish, as they call it, is super tough. I haven’t even scratched it. Also, I had a QD point mounted to it and when I removed it, you couldn’t even tell it was on the handguard. It didn’t even leave a chip or indent. I kind of wish the Darklite had a QD point built in. That way I could connect a sling without adding the weight of the QD mount. The black color of this E-Cote finish matches the rifles anodizing very well and I like the durability of it.

  Installation of the Darklite handguard is pretty normal also. Install the barrel nut with the supplied wrench. YES, it includes a wrench! This is one of my favorite things. Every other manufacture, please do like Dark Hour Defense and include a barrel nut wrench with your handguards. The barrel nut may or may not need shims, mine was on the tight side without them, but still in specifications for torque. When installing the handguard tube, you may need to tap it on with a rubber mallet, or heat it up slightly. It is a nice snug fit. I just tapped it on and it worked fine. Dark Hour also includes a locator pin, so if your upper has this provision , you can use it for added rotational stability. I didn’t use the pin and have not had any problems with the handguard rotating. Lastly, install the 6 torx screws to spec, and off to the range you go.

  As usual, I’ve been trying to use the Darklite as much as possible. I really like it, but I like slim handguards, and at 1.5”s, it is just perfect. The Darkilite is a no frills, super lightweight handguard. They smoothed it all out and put angles and radiuses where they needed to be, like on the muzzle end of the handguard. The top rail portion is even pretty smooth, which is not an easy task with all those slot cuts. The price won’t kill your wallet either. At $195 for the 9.2”, it’s a great deal. Yes, longer ones cost more, but they are still a reasonable option for what you are getting. 

  The Dark Hour Defense Magnesium Darklite handguard is well worth checking out. You are definitely getting a quality lightweight handguard at a reasonable price, at least in the lightweight product category. I think Dark Hour Defense will be doing some more nice stuff in the future. Definitely keep your eye on them for cost effective lightweight products.

RMT Nomad Trigger

  The trigger market is flooded with good AR triggers. To stand out, you need to think outside the box. RMT Triggers has done just that with their Nomad trigger. The Nomad has a pivoting and rotating trigger shoe. Yes, the trigger actually pivots to fit to your finger placement on the shoe.

  As mentioned, the first noticeable difference in the Nomad trigger is its moveable trigger shoe. The trigger shoe is free floating, so to speak. It will pivot and rotate up to 6 degrees off of center. This will place the trigger shoe exactly where it needs to be on your finger. If your finger is a little short or long, it rotates to give your finger pad a perfect contact point on the trigger face. Maybe you don’t have a perfect grip on the rifle, the Nomad will also pivot for better finger pad contact. 

  The Nomad uses a flat face trigger. This works very well with the pivoting system. I typically don’t prefer flat faced triggers, but the Nomad is really nice. It’s called a flat trigger, but in reality, it has an ever so slight curve to it. This very slight curve might be why I like it more than other flat faced triggers.

Notice that the trigger is pushed out toward the edge of the trigger guard, due to it’s pivoting system

  When I, and others, first felt the Nomad trigger we thought it was a little odd. This was because of the noticeably left and right movement. This completely went away when we shot the actual Nomad. When shooting a rifle with the Nomad trigger in it, you don’t even notice that the trigger pivots and rotates to fit you. The Nomad just does what it does, adjusts to you and how you shoot. The trigger is also very fast to use!

  Now that the exotic parts of the Nomad are out of the way, it is still a drop in trigger. The Nomad is your typical cartridge style AR trigger. This makes installation super easy. Just remove the old trigger, pull the grip off, slide out the safety, then drop the Nomad in. The trigger comes with a set of anti-rotation pins, which are needed for installation and are something I recommend for cartridge style triggers. So the pins being included is a bonus in my eyes.

Notice how trigger is rotated.

  Besides the free adjusting trigger shoe system, the Nomad is a good feeling trigger. As mentioned before, I like the shape of the trigger shoe. The pull has a tiny bit of pre-travel, followed by a fairly short break , with little to no over-travel. Total trigger travel is around 0.125” measured at the bottom of the trigger shoe. My only complaint with the Nomad is its gritty pull. When pulling the trigger slowly, you can feel the grittiness in it. It hasn’t gone away either, even with over a thousand trigger presses, thanks to the Mantis Blackbeard. The Nomad is still a very fast trigger to shoot. When pulling the trigger at anything other than a slow pace, the grittiness is not noticeable. Part of the reason the trigger is fast is its great reset. The other reason is its 3 lb pull weight. I can shoot the Nomad on par with my other “fast” triggers. I don’t even notice the pivoting shoe when shooting fast or slow. The Nomad I received consistently has a pull weight of 3lbs 2ozs. 

  I’ve put a bunch of time in on the RMT Nomad trigger. I’ve had other people try it out. In the end, everyone seemed to like it. I think RMT has a really good idea going with the Nomad trigger. It may seem a little expensive, but you're getting a quality trigger PLUS something that can help you pull that trigger, wherever your finger decides it wants to be placed on it. At first the RMT Nomad may seem odd, but give it a chance, and you will see what it is all about.

Red's Review of RMT Triggers Nomad Trigger

Fascinated by the concept, but skeptical at first. Buddies tried to convince me to go with something else, cause they thought “it would exacerbate bad habits.” Now here I am having the last laugh. Shooting this trigger compared to my buddies, my groupings are significantly tighter, and now they want one! Definitely worth every penny. I still shoot well with other triggers, I just shoot even better with this one. If you are looking for the competitive advantage, this trigger gives you it!

Pros:

  • Crisp break

  • Short reset

  • really well made

  • The trigger adapts to me

  • No need for finger gymnastics or awkward gripping

  • improved my groupings

Bushmaster DM2S Trigger

  I'm not usually a 2 stage AR trigger guy. So when Bushmaster asked me to review one of their new DM2S triggers, I was a little hesitant. But, since I really like trying different triggers out, I couldn’t pass up the opportunity. When it showed up, I was pleasantly surprised with how much I liked it. The DM2S is a good 2 stage AR trigger.

  If you haven’t heard, Bushmaster recently came under new ownership. What does that mean for you, the consumer? Most likely they will be introducing new products, like the DM2S, suppressors, and new updated rifles. All made in America.

  The DM2S is a little different then most aftermarket triggers you might be used to. It is not a cartridge style. Instead it resembles a Mil-spec trigger. So when you install it, it installs in two pieces, just like that old GI trigger. But, it is definitely not your old GI trigger. However, the trigger shoe is a spot on match for a GI trigger. So the trigger shoe curve will be recognizable to all. In fact, when you look at the exterior of a rifle with the DM2S trigger in it, you can’t even tell that it has a match grade trigger installed. 

  I guess an explanation of what a “2 stage” trigger is, is in order. A 2 stage trigger has 2 distinct actions. When you first pull the trigger, a lighter weight pull is felt. This lighter pull can feel like take-up, but in fact, it is part of the design. Once you pull through the first stage, you come to a stop, or wall. This is the second stage. The second stage is a heavier pull weight that is added onto the first stage's pull weight. Then you add a little more pressure, and the trigger breaks, thus firing the firearm. 2 stage triggers are sometimes used by those wanting to “stage” the trigger to get that little extra accuracy. By pulling through the first stage, a shooter can then make slight accuracy adjustments before breaking the shot. Or if the shooter decides not to take the shot, they can simply just release pressure to reset the trigger back to its original starting point. The DM2S that is here, measured around 1.5 lb pull for the first stage and 4 lbs for the second stage. So the DM2S’ second stage adds 2.5 lbs to the first stages 1.5 lbs, thus giving the total pull weight 4 lbs. Bushmaster publishes lubricated and unlubricated pull weights, listed in the FNB’s down below. The 4 lb weight, I measured, was with a lubricated trigger. It was only slightly higher before I lubricated it, maybe 0.25 lbs heavier. The DM2S’ second stage pull is crisp and clean. I was pretty impressed with the trigger break. It also has an excellent reset.

  As mentioned, I’m more of a single stage trigger guy. However, the DM2S isn’t something to turn away. I was pleasantly surprised at how fast I could shoot this trigger. I ran some rifle Bill drills with it and they were about 0.30 seconds slower. That’s 6 shots on target at 7 yards, in 1.7 seconds with the DM2S. Not quite as fast as a super light single stage, but still fast. I can also see where the 2 stage has advantages when shooting from a bench, or prone, or for accuracy. Staging the trigger and then pulling through the 2nd stage can really help staying on target. With the trigger only having a pull weight of 4 lbs, it doesn’t lend itself to moving you off target like a heavy trigger pull weight can.

  The DM2S is a non-adjustable trigger. There is nothing to set for pull weight, over travel, or anything else. That being said, the DM2S has a little bit of over-travel, but not much, maybe 0.050”. Since it is a 2 stage trigger, pre-travel is included in the first stage. I did measure it at around 0.150”. The trigger break measured a little under 0.100”, so I’d say about .080”. Therefore, the total trigger movement, to get the trigger to fire, is around 0.230”, or just under ¼ inch. Reset on the trigger seemed to be around 0.100” since you don’t need to reset the trigger all the way through the first stage, only to the beginning of the second stage.

  The DM2S trigger, from Bushmaster, actually surprised me. For a 2 stage, dedicated marksman style trigger,  it is pretty good. The pull weight is good, it has a crisp 2nd stage, and a forceful reset. If you are the type who likes 2 stage AR triggers, you might give the DM2S a try.

Blackout Defense Zero Trigger

  When people that have been shooting for a while ask me for the best upgrade, I usually tell them a good trigger. For newer shooters, it’s dry fire practice, but that’s a different story. Since I’m on the trigger subject, Blackout Defense has come out with their Zero trigger for the AR15 and AR10 platforms. Blackout Defense sent me a curved shoe trigger with a 3lb pull. This is one of the best single stage triggers I’ve had the pleasure of using.

  When you first see the Zero trigger, you don’t really notice anything different about it. The differences are on the inside, and become quickly apparent, more on that later. First off, it’s a cartridge style “drop in” trigger assembly. This makes installation easy. I’d recommend the anti-walk pins, as I would with any cartridge style trigger. They just give that little bit of added security, even if it’s just in my mind. As mentioned, I opted for the curved trigger. The curve is not near as much as a stock GI trigger. I would call it a short radius, but it’s appears to be a pretty standard profile for aftermarket triggers. I really like the curved profile, it works really well for me. If you don’t like curved triggers, they make it in a flat profile too. For me, the curve gives a consistent finger placement, so the felt pull is always the same.

  Now for the Zero trigger internals. What makes the Zero trigger so unique is its ability to completely remove pre-travel and over-travel. So much so, that the total trigger movement can be set to 0.078”. Part of this is accomplished by a curved or cupped trigger tail. This “cup” allows the tail to cradle the safety drum. To fully adjust, or get rid of, the pre and over travel. Hardened set screws are installed on the bottom of the trigger housing, both at the front and the rear. From Blackout Defense’s website - “The bottom of the Zero™ trigger housing features threaded holes that straddle both the front and rear of the trigger tail.  Hardened set screws are provided and can be installed through these threaded holes to finely tune the trigger location and push it into contact with the safety.” The trigger tail riding on the safety drum is what eliminates the pre-travel and is adjustable through the rear set screw. The over-travel is then adjusted with the front set screw. Once set, red loctite is recommended to keep them from moving. My only complaint about this process is that it is tedious work. Mainly because you have to pull the trigger out, turn the set screw a tiny amount, then reinstall the trigger and try it again. Be patient, it could take a while. The Zero trigger is so well made, that these tedious adjustments aren’t really needed for a great trigger pull. I just needed to see how it was done, as it is an option. The trigger will fit in any mil-spec lower, but if you don’t want to take the trigger in and out to adjust it, Blackout Defense’s lower receiver has 2 small holes in it, so that you don’t have to take the trigger out for this adjustment. The Zero trigger also has two different finish options for the internal components. Either Black Nitrided, or NP3. Both finishes help with lubricity and corrosion resistance. After factory setting the trigger pull weight, Blackout Defense then arc welds these set screws to make sure that they never come out of the factory adjustment. Note: these are different from the set screws used to adjust the pre and over travel, these are the ones the factory uses to adjust the pull weight (see inside the trigger housing picture). As you can see, those two screws aren’t ever moving.

  Two different trigger pull weights are available from the factory. Either a 4.5lb pull or a 3lb pull weight. I opted for the 3lb pull weight. When I measured it, it is consistently under the 3lb mark. Anywhere from 2-¾ lbs up to just shy of 3 lbs. Follow that up with the super short pull and the super crisp break, it feels like less. The reset on the Zero trigger is also great. Super crisp and tactile. The reset impressed me for a 3lb pull weight trigger.

  The Zero trigger has me sold. It is one of the best single stage AR triggers out there, at least in my opinion. It works spectacularly when shooting fast. I can consistently shoot a rifle bill drill (6 shots, A zone hits, 7yds) 0.25-0.30 seconds faster then when I use the same upper with different triggers. It works really well for precision shooting also. Having that short crisp pull allows me to not disturb the rifle when pulling the trigger slowly. Does it help my groups? Who knows, but I do know it’s easier for me to not move the rifle.

  While running the Zero trigger, I put a lot of time into dry fire. Well, maybe not dry fire, but the Mantis Blackbeard. This gave me the thousands of trigger pulls I needed to really fall in love with Zero trigger. The trigger never had a single hiccup, either dry fire or live fire. The super fast reset and crisp break made it a dream to use with the Blackbeard system. 

  When it comes to aftermarket triggers, the Zero trigger is a gold mine. This trigger does everything I want in a good AR trigger. Yes, the light, short pull may not be for everyone, but if you are looking for a super fast trigger, it might just be for you. Having the ability to have ZERO take up and overtravel really makes the Zero trigger shine. If you are looking for a great trigger for your AR, I would definitely give Blackout Defense a call. They are super helpful if you need any questions answered about the Zero trigger, or any of their other products.

SPOOKY PERFECT TRIGGER

I shot National Match Competition on the USMC Shooting Team at Quantico “back in the day”. We fired highly-tuned M-14’s built by amazing craftsman.

Everyone was obsessed with trigger performance.

This is the trigger we were always chasing, only better.

First, there really is no takeup. Apply 4.5lbs with absolutely zero creep. The trigger breaks clean, moves about .05″ and stops.

Release the trigger and it resets: click. Press again. Zero creep, breaks at 4.5lbs, and stops dead. All. Day. Long. Absolutely consistent. It’s uncanny.

After the Marines, I worked my entire career with High Tech CNC manufacturers. So, I know what it takes to make something great: engineering, equipment, people, and quality control. It takes them all.

Hats off to Customer Service too: fast, friendly, efficient, responsive and effective. Thanks.

Does this sound like a paid endorsement? It isn’t. I paid full retail for the NP3 All with Trigger Pins direct from the Blackout Defense webstore.

I am just an ex-Jarhead who knows that you (often, hopefully) get what you pay for. In this case, I got more than I thought was even possible. Nice upside surprise.

To my fellow trigger-obsessed perfectionist, you won’t be disappointed.
