Enoch Industries is enhancing the Ruger 10/22 market with their chassis systems. They manufacture 2 different ones, the Odin and the Deep Six. Thanks to Faxon, and their rimfire barrel, I was looking for something that would compliment it. Odin offered up a Deep Six in PEWter. Since the Deep Six is longer and better suited for what I was doing, I couldn’t say “no”.

The Deep Six is made for 10/22 style rifles and pistols, but not the take down versions. I used a stock Ruger 10/22 rifle action, but pretty much all of the aftermarket ones will work too. Mounting the barrelled action into the Deep Six is just like mounting it into any other 10/22 stock. The only difference is that Enoch supplies a proprietary screw to hold the action in place. This screw is essentially just a short version of the stock 10/22 mounting screw. I put some threadlocker on it before I screwed it down tight. After tightening the screw, you can actually feel how much more rigid the chassis is over a stock. It’s just a real solid fit, and that screw comes up tight unlike the factory style.

Enoch Industries has made the Deep Six longer than their first chassis, the Odin. It is still short enough for pistol length builds, but I feel it really shines for the more standard rifle length builds. The total length is 15.5 inches. This doesn’t really say much, since that is without any support device attached to the rear rail. What does matter is the 2.5” added length to the forearm over their Odin chassis. This allows for a forearm length of just over 7 inches. Plenty enough to get a good grip on the rifle, as well as maybe install a bi-pod or grip panels. Along the forearm are 3 full length M-Lok slots to aid in adding those accessories. The slots are on both sides as well as the bottom. The Deep Six also allows for almost any barrel profile or barrel addition one might be after. They opened up the forearm to accept barrel diameters of up to 1.310 inches. This means that any bull barrel will fit. Or, if you have a really short barrel and want to run a suppressor, the suppressor will most likely fit in the handguard area!

Besides being a lightweight aluminum chassis, Enoch added a few bonuses into the Deep Six. The first notable one, is the addition of 2 steel QD inserts. One on each side, on the rear of the chassis, behind where the receiver sits. These work really well for pistol configurations, as a sling can give you some extra support when shooting. For a rifle, they just give you another location for sling mounting. Second, is the addition of a built in filler, behind the trigger guard and extended to the pistol grip. It fills that gap so your hand doesn't get pinched. Not all 10/22 chassis’, that use pistol grips, have this. It really does help and it makes the chassis look complete.

Yes, you will need to add your own pistol grip to the Deep Six. All non-beavertail grips will work. If you want to use a beavertail grip, it may have to be modified. I modified a beavertail grip for use on it, I just cut the beavertail back some and it works great. I even tried some 3D printed ones that worked too.

As for mounting a stock or brace, the Deep Six has you covered. The Deep Six uses a 3 slot picatinny rail for mounting these. This type of mounting system is becoming more and more popular, especially on 22’s. With the picatinny rail, the user has many options, from fixed stocks to folding braces. Being that I was doing a “rifle”, I opted for a fixed stock from Occam Defense. This stock is a little shorter than some other options, which actually makes it ideal for me on this chassis. It makes the length of pull a little under 12 inches. The Occam stock uses a 4 slot mounting, so there was a little extra sitting above the 3 slot rail on the Deep Six. Besides looking odd to me, it fit and worked great. I did end up printing a spacer to fill the space and make it look seamless.

The Deep Six is a well thought out chassis. The PEWter color has a nice grayish hue to it, which enhances the other parts installed on the rifle. The edges are smoothed out, but still sharp. The fit of the action is much better than most other stocks out there. So as you can guess, the machining is top notch with no noticeable machining marks. There is also an Enoch Industries logo machined onto the left side of the chassis. No names, just the logo. Along with that, there are also machined recesses that give the chassis a distinct look.

Enoch Industries did a great job with the Deep Six. It’s short enough to be used on a pistol, yet long enough to look good on a full length rifle. The combination I am running turned out fantastic. When using the Deep Six, you can pretty much build any 10/22 your imagination can come up with. I really do like what Enoch has done with the Deep Six. Definitely check out Enoch Industries and the Deep Six chassis. I really can’t say enough good things about it.

After winning a Savage 11 at a raffle, I was looking around at what I could do to it. I started looking at chassis for it and ran across Modular Driven Technologies (MDT for short). I contacted them and they said they would send me a chassis for review. They sent me the LSS-XL, their new lightweight stock, and one of their AICS pattern magazines.

The LSS-XL is an all aluminum chassis that can use AR stocks and pistol grips. It comes either cerakoted black or FDE. It can use their stock also, which I'll talk about later. Since the chassis they sent me was for a Savage, I'll talk about it, but all of the LSS-XL's are basically similar. The first thing I noticed was the nice sized paddle magazine release. It has good spring pressure and is easily accessed to remove a used magazine. I also noted that it came with a sling swivel stud mounted, perfect to attach a bi-pod on. Next up is the trigger guard that has enough room for gloved hands, but is could be larger. The stated weight is 1.8-2.1 lbs, which is just the chassis without a stock or pistol grip. My scale broke, so I am taking the weight off of the MDT website. Now the LSS-XL has a longer forearm than the LSS, but it is about the same length as the stock forearm. Even though the chassis is about the same length as the factory stock, it is much thinner and is flat on the bottom and sides. It also has plenty of mounting holes on it. These holes are spaced to fit Magpul L3 or L5 rails. Of course MDT makes rails to fit also. On the Savage style chassis, it has a slot in the side above the trigger. This slot is for Savage actions with a bottom bolt release. After installing the LSS-XL, to remove the bolt, you have to now put a pin, nail, screwdriver, or whatever in this slot and move it rearward to remove the guns bolt. The chassis also comes with a little spacer washer, that you install on the front bolt, depending on which action length you have. Older Savage's have a slightly different bolt spacing on the action than the newer versions. Using a rounded inlet with flat spots, for the action to ride on, this design is said to aid in accuracy and strength. Along with this system, the chassis can accept barrels up to 1" diameter while still free floating the barrel.

One of the great advantages to the MDT LSS-XL is it ability to accept the AICS style magazines. The stock magazines that come with the Savage are junk compared to the MDT magazine. MDT's magazine is polymer and holds 8 rounds of .308, .243, .22-250, or 6.5 Creedmoor. They also make a magazine for the smaller .223 rifles. My rifle is in .243 winchester, and the magazine function was flawless. I am also able to get 9 rounds in the magazine and still have it function. Being that the LSS-XL uses the AICS pattern, I also tried a Magpul 5 round AICS magazine. It did not lock in place at first. I modified it slightly by removing some plastic in front of the feed lips and now it works also. Basically I made it look like the MDT magazine.

Along with the chassis, MDT also sent their "Skeleton Rifle Stock Lite." This stock is meant to compliment the chassis, and it does a decent job of it. The stock is adjustable for length of pull and cheek weld. Now it does not have infinitely adjustable screws, instead it has notches in the riser and buttplate mounting stems. The buttplate and riser are moved by pushing an elongated button, and then moving them to the desired adjustment. I really liked this button system as it was easy to use, and held the plates in firmly. MDT also makes the stock out of aluminum and it is cerakoted to match the chassis. Another nice touch on the stock is its ability to accept mounting rails like the chassis. This makes it possible to install a monopod or such device under the stock. As with most stocks these days, there are also built in sling swivel cups. One problem I had with the lite rifle stock was the rear but pad and cheek riser get in the way of cleaning your rifle. Even if you take the cheek riser off, the design makes it impossible to run a cleaning rod straight through the rear of the rifles bore. If you want to do this, you must actually remove the stock completely. I did not have the same problem when using a standard AR stock.

There are a couple of items to note. The stock's length of pull was too short for me even when the buttplate was fully extended. And there is no radius where the top of the grip meets the stock. AR grips with beavertails don't really work. So it kind of pinches your hand between your thumb and forefinger. I noticed it more with a collapsible AR stock. The MDT stock was way less noticeable.

The MDT LSS-XL chassis, Skeleton rifle stock lite, and magazine make for a really nice stable shooting platform. MDT offers these chassis for lots of different rifles, and all of them at a very reasonable prices (for a chassis system).
