BCM MCMR-13 13.4″ M-LOK Free-Float Handguard, Black

Description

The Bravo Company (BCM) Gunfighter MCMR-13 is a free-float modular rail designed for AR-platform rifles. It uses an M-LOK compatible mounting system to provide modular accessory attachment while reducing barrel loads to help maintain consistent barrel harmonics. The MCMR series incorporates BCM’s proven barrel nut and lock-up design and a mechanical index at 12:00 to help stabilize the rail under thermal cycling. Constructed from precision-machined aerospace-grade 6061-T6 aluminum, the handguard is finished with a hard-coat anodize for corrosion resistance and surface durability.
