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 a 11in cmr on a 12.5 centurion arms carbine barrel . It had very tight fit up and extremely nice finish. Its very ergonomic not so thin it feels weak and not so thick its hard to hold. Havent noticed any problem with heat . I have bought again and referred others to check them out. On a company level i have never dealt with more professional, curtious and knowledgeable staff.
A great system that fit perfect with my 14.5-inch barrel pinned and welded. The attachment system is great and the gen2 is even lighter!
Top notch. Handled a buddies carbine yesterday that has this rail. Perfect balance of weight and size with enough gas block clearance inside. The CMR has stood the test of time and existed way before small light weight rails were a main stream thing. All the features you need in a bomber package that's sexy. My next build will have one.
I put a 13" CMR on a build using Centurion's CM4 upper/lower set and really like the compact size and light weight of this rail. The length is perfect with the 16" barrel I used. I'm not a fan of bulky rails with a bunch of accessories mounted on it so this piece is perfect for my preference in a build. Like the old TV commercial used to say....try it, you'll like it.
Centurion Arms is a fantastic company! I bought a 13in. CMR for my AR assembly, (my wife's, she wanted light...) the Magnesium lower started off the project. I contacted Centurion Arms, the CMR 13 inch looked like a great fit! The CMR arrived with in the week! I forgot to order the rail covers. I jumped back on the web site ordered
The FDE, .(manadatory for Arizona shooting!) Two days later they arrived at the door, and were on her carbine. She loves it! The slim grip, the texture on the slim line panels, it fits her perfectly! The folks at Centurion Arms are great people, they put out a quality product, stand behind what they make, and do all they can to help you succeed! I really appreciated the personal note of thanks on the receipt. My next assembly will definitely have a Centurion Arms rail, that's for sure
I have one of these rails set up on a 16” build I made about 4 months ago. I love this rail. It’s incredibly solid and extremely slim. Makes for a great lightweight build without sacrificing durability.
Love the original CMR. Have had it for a little while and it’s perfect for my colt commando. Thank you Centurion!
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.
