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 and using the MLOK mounting system. 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.
***Current CMR MLOK models are DPMS high pattern receivers***
