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 7.62/.308 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, barrel nuts and wrenches are included with the purchase of these rail systems. Replacements are available to purchase if necessary.
In spite of this not being what I truly wanted, I settled since it was available. The turn around from time I placed my order to getting notification it shipped to receiving it was awesome. I was not able to find the so called blemish which made this even better. After I attached this to the Aero 308 upper, it was a marriage made in heaven. I have no regrets in getting this and it was well worth the purchase. I would recommend this for anyone's build. I'd buy it again!!! Excellent part!
Easy install ,for a aero upper small modification to the anti rotation block .great product way better than mlock or keymod .I purchased the blem and I couldn’t see a defect .looks bad ass and I can’t wait for my accessories..great product and great service I’m glad I stumbled across centurion arms .I will be upgrading some of my other rifles with centurion.
Ok..... so I have an addiction to Centurion Arms rail systems but hey atleast I admit it. I was building a 7.62 upper for my son on an Armalite platform 7.62 CMR and having seen the results on that build that is what started me down this path to having my own on an Aero Precision M5 upper. As I have said on my 5.56 CMR reviews the rail is slim and with the tangs it locks up solid to the upper receiver allowing for perfect alignment. Lastly as on the 5.56 versions the barrel nut design is simple and easy to work with.... no timing to worry about, it just flat out works.
