This week at SHOT Show in Las Vegas, Centurion Arms sneakily introduced two new versions of their extremely popular CMR rail in the Magpul and BattleComp booths. The CMR rail is a very slim, rugged, tubular rail. It features threaded holes every couple of inches to bolt the CMR rail covers, hand stops, etc to but most accessories made by other companies are designed to attach to 1913 quad rails, KeyMod rails or M-LOK rails. Now you can get the CMR in your choice of KeyMod or M-LOK as well.
Now that you can choose KeyMod or M-LOK, it really opens up a whole new world of usable accessories you can attach to your CMR rail. I’ve got a ton of grips, light mounts, hand stops, rail sections, rail covers, etc. just waiting for an awesome rail like this. I immediately installed the CMR M-LOK rail on my CIV Tactical SPR build. The ability to add a picatinny rail for my bipod via M-LOK (or KeyMod for that matter) is quick and painless.
The overall profile of the new CMR KeyMod and M-LOK rails is very similar to the original CMR and still features anti-rotation tabs. The barrel nut is also very similar, in fact the new rail will mount to an older CMR barrel nut, but Centurion Arms actually modified the new barrel nut to be able to tighten them using a standard AR-15 castle nut wrench.
The production model CMR KeyMod and M-LOK rails will have QD Sling Mounts at the front and rear of the rail on each side just like the original (the ones in my photos were pre-production) and will be available in both 15″ (shown) and 13″ models.
MSRP on the new rails will run $240 for a 15″ and $230 for a 13″. Centurion Arms will start taking pre-orders at the beginning of February at an introductory price of just $200 for a 15″ or $195 for a 13″ and start shipping units around the end of February. Centurion Arms is an awesome company owned and operated by a retired Navy SEAL. Lets show them some support!
