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 these rail systems. Replacement screws, barrel nuts, and wrenches are available to purchase if necessary.
I have one of these on my pistol build with a 10.5" barrel and the end result was great. With a suppressor mounted it's hard to tell where the rail ends and the suppressor begins. This rail is lightweight and slim, My MK18 is a tank compared to this upper. The tangs allow the rail to lock up solid to the upper receiver allowing for perfect alignment. Multiple QD connections are and added plus saving me the expense of add-on QD attachments for a sling. And lastly as I've said in my other reviews for Centurion Arms product the barrel nut design is simple and easy to work with.... no timing to worry about, it just flat out works.
