The Centurion Arms CMR Rail is a lightweight, rugged, one-piece free float handguard that uses a proprietary barrel nut and gives an AR upper a continuous 12 o'clock rail. 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. Accessories can be directly mounted to it with a dedicated, simple, light-weight mount or a conventional 1913 rail section to be added and used if needed. Additionally, the CMR built-in anti-rotation QD sling swivels in 4 positions. The main objective was to have a smaller, lighter weight, more ergonomic K.I.S.S (Keep It Simple, Stupid) handguard that maintains or enhances functionality for the end user.
