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.

Reviewer: Brody from utah  
I had purchased the c4 rails for other projects and had no problem feeling confident in purchasing the mlok rail when it became available. It locks up tight and has built-in QD mounts. I have put this on two rifles.

Reviewer: Chad from Colorado  
Out of all the rails I own, the CMR is definitely one of my favorites.  The slim profile, secure fit and excellent finish make it one of the best out there.  Centurion is a great company to order from, fast shipping, great correspondence and great products.
