Back in June Enoch Industries announced their 10/22 Odin Chassis. I was excited and a little annoyed at the same time because I had just bought a PMACA chassis for my Ruger Charger. Well, an opportunity arrived and we got the Odin Chassis in for a review.
Chassis All The Things
I bought a Ruger Charger specifically for the purpose of putting it in a chassis. The takedown version of the Charger is actually more limited in options for a modular chassis system. As I mentioned earlier I originally purchased a PMACA chassis for my Ruger Charger. Before the Odin Chassis, the PMACA met most of my needs. I was able to have a folding brace on the chassis with a rail to add a light/laser.
The rear of the PMACA chassis is threaded to accept an AR buffer tube. I used a folding adapter from SB Tactical to get the buffer tube to fold. This works but the problem with this setup is the fact that the Ruger Charger does not need a buffer tube to function. It is just used to attach the stabilizing brace. As you can see in the photo below the brace and tube are rather thick. Thicker than the PMACA chassis itself. The other issue is that the hinged adapter does not stay open very well. There is no detent to keep the hinge open so the brace slaps against the side the chassis. Or the brace will fold open under its own weight.
The other problem I have with the PMACA chassis is the lack of side rails to attach a light or laser. Yes, I could attach it to the bottom rail but that is very limiting in terms of options.
10/22 Odin Chassis
Now compare the PMACA to the Odin chassis. It is similar in function. It is an aluminum chassis that allows you to use AR-style grips but it adds a bunch of modularity and features that the PMACA lacks.
Side by side they are very similar. However, the devil is in the details. Starting at the front of the 10/22 Odin Chassis you will notice that there are two MLOK slots at 3, 6, & 9 o’clock. This allows you to mount almost any accessory you want. If you want to attach a bipod, light and laser to the Odin Chassis, well you can.
Near the rear of the chassis, there are QD inserts on both sides. One minor issue, and the PMACA chassis suffers from this same problem, is that you have to use flat AR-15 pistol grips like a Magpul MIAD or A2 grip. If they have a beaver tail then you need to cut them off to fit the chassis. I modified my Reptilia CQG pistol grip to fit.
The most desired feature of the 10/22 Odin Chassis is the short Picatinny rail milled into the back. This allows you to use MPX/MCX style braces or stocks. I prefer those stocks and braces since they are exceptionally narrow. They are thinner than the Odin Chassis so when folded the whole gun is still very thin.
Since the Ruger Charger is a pistol, I opted for the SB Tactical FSB1913 brace.
Things To Be Aware Of
The Odin Chassis is a bit wider than your 10/22 receiver. While it is not a big deal, it is possible to have the barrel sit closer to one side than the other. So just pay attention to where the barrel is when you are tightening the receiver screw.
What is more important is the amount of gap on either side near the back of the receiver where the bolt stop pin sits in the receiver. My Ruger Charger had a very loose bolt stop pin so I could hear it slide side to side hitting the 10/22 Odin Chassis side walls. It got annoying really fast. However, I had a Delrin bolt stop pin that I had made a while back and when I replaced the bolt stop pin the sliding stopped. You could also tape the bolt stop pin or shim the gap with some material to take up the slack.
If you use the 10/22 Odin Chassis on a rifle setup or SBR setup then you may choose to go with an MCX/MPX style stock. There is something you should know about the factory MPX/MCX hinge.
Due to the design of the factory SIG MPX/MCX hinge, the hinge protrudes downward and it will interfere with your grip.
The solution is to unscrew the Torx screw that attaches the hinge to the stock. Then rotate the hinge 180° and retighten the Torx screw. This will put the hinge on the right hand side making the stock fold to the right but now the hinge protrusion is pointed upwards.
Fortunately, the MCX adjustable stock fits beneath the stock Ruger 10/22 charging handle. I imagine if you tried to pair this setup with one of those Volquartsen straight pull Summit actions then the large charging handle will get in the way of the folding stock.
Final Thoughts On The Odin Chassis
The PMACA chassis was fine until Enoch Industries showed me the light with their 10/22 Odin Chassis. It has all the features I wanted the PMACA to have. The only difference is the price. The PMACA chassis starts about $100 less than the Enoch chassis. However, it depends which PMACA chassis you get and what options you add on that will cause the price to increase. Just the folding buffer tube adapter by SB Tactical that I used on my PMACA costs $150. That is more than I paid for the PMACA.
The Odin Chassis retails for $225. Although at the moment of typing this review the Odin Chassis is on backorder. You can buy blem chassis for $190 from Enoch Industries website. One minor issue with the Odin Chassis is that they are only offered in black anodizing at this time. Whereas the PMACA chassis comes in ten different colors: three anodizing colors and seven Cerakote colors.
As I mentioned earlier the PMACA chassis lacks in features. It does not have ambidextrous QD inserts and only one accessory rail at the bottom. The Odin Chassis has QDs for slings and MLOK slots on all three sides of the chassis forend. Add the fact that you can use folding braces or stocks to your heart’s content makes the Enoch Industries Odin Chassis the better option for me.
