Description

The Bravo Company BCM MCMR is an 8-inch M-LOK compatible free-float handguard designed for AR-platform rifles. It is precision machined from aerospace-grade 6061-T6 aluminum and finished with a hard coat anodize. The handguard uses BCM’s patented mounting system and a steel barrel nut to maintain a secure mechanical index at the 12:00 rail. Its profile and mounting geometry are engineered to offer modularity with M-LOK accessories while minimizing heat-related movement.
