The Century Arms patent pending CMR is a free float rail system for AR-15 platform rifles. It attaches by clamping on to a proprietary barrel nut (included) and provides the upper with a continuous Picatinny rail at the 12 o'clock position. Other accessories can be mounted directly to the CMR with a dedicated, simple, light weight mount, or sections of 1913 Picatinny rail can be added as needed. The goal was a smaller, lighter weight and more ergonomic hand guard that maintains or enhances functionality.
