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 and proprietary barrel nuts are included with the purchase of all rail systems. Replacement screws and barrel nuts are available to purchase if necessary.
Great MLOK rail, functional and great quality. measurements were accurate, QD mounts functional, and overall a very solid product.
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.
Light weight quality product. Will purchase again
Fit and finish, profile, and durability of rail all superb. Customer service and response time is also outstanding. Own numerous CA products and always impressed with quality. Highly recommended.
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.
Ever since I picked up the original CMR rail, I hoped Centurion Arms would come out with a MLOK version. The diameter of these hand guards is perfect IMO. I dig how simple and strong all of their hand guards are, and now they come in MLOK flavor! These are the only hand guards/rails anyone needs.
This rail came on the complete upper I bought, it is robust yet slim. You'll have no problem getting your hands around it for a positive purchase. Mounting system looks and feels very strong.
Lightweight, slim in the hand, and most importantly , sturdy . I have this Rail on my CM4 and the same Rail on a 16" build. Totally happy with Centurion Arms products .
