Our patented CMR rail system is a lightweight, rugged, one piece, free float hand guard that, when installed, gives the upper a continuous 12 o'clock rail. The CMR system clamps to a proprietary barrel nut that can be installed on 5.56/.223 based AR platform systems. It was designed with the top 1913 rail for mounting the most common accessories, yet does away with the need for 1913 rail at the 3, 6, and 9 o'clock positions. Here, other accessories can be directly mounted to it with a dedicated, simple, light-weight, mount. However, it does allow for 1913 rail to be added, if needed, for some less common accessories. Additionally, we built in anti-rotation QD sling swivels in 4 positions. The main objective was to have a smaller, lighter weight, more ergonomic, hand guard that maintains or enhances functionality for the end user. As professional end users ourselves, we know the importance of keeping things simple and that was our design intent here... a K.I.S.S. (keep it simple, stupid) system.

***IMPORTANT PLEASE NOTE***
- Currently our gas block is the only one that Centurion Arms can guarantee to fit under the CMR. This is due to the CMR's extreme low profile.
- Screws, proprietary barrel nuts, and wrench are included with the purchase of all rail systems. Replacement screws, barrel nuts, and wrenches are available to purchase if necessary.
install was straight forward.
definitely will be ordering more from here.
Rail installed painlessly
looks killer with the 11.5 barrel
will definitely buy more of centurion arms products
Very nice product strong and reliable
Solid lock up. Slimmest profile I’ve handled. Feels great in the hand. I suggest the small mlok screws. If you have a heavier profile barrel the long ones can make contact with it. Quality piece for sure
Great low profile rail, it arrived in a very timely manner after order was placed. Customer service is top notch.
Easy to install, fit and finish is top notch! The CM4 is definitely in my top 5 best Rails.
Excellent rail; lightweight, extremely sturdy, easy install. Only has Mlok slots on 3/6/9 O'clock positions but that's really all you need. Only gripe is the included barrel nut wrench is cheap and the teeth started stripping when torquing down to 60ft/lbs as instructed
Awesome, light, small diameter rail that feels great in hand. Love the new 2 screw mounting design. Ordered a 13.5" in OD green and it turned out beautiful. You can find cheaper rails but you won't find higher quality than Centurion. Money well spent.
