This 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.
With this slimline design and a mixture of Picatinny and M-LOK sides, other accessories can be directly mounted to it with a dedicated, simple, light-weight, mount. Additional 1913 rails can be added to the M-LOK surfaces, if needed, for some less common accessories. Additionally, Centurion builds-in anti-rotation QD sling swivels in 4 positions. The main objective is to have a smaller, lighter weight, more ergonomic, hand guard that maintains or enhances functionality for the end user. As professional end-users, the guys at Centurion know the importance of keeping things simple and that was our design intent here... a K.I.S.S. (keep it simple, stupid) system.
This is a variation on the Centurion 1513, but does not have the QD socket, otherwise pretty much the same
