Bravo Company MCMR-13 Black M-LOK Handguard

The Bravo Company MCMR-13 is a black 13 in free-float handguard that brings BCM’s MCMR mounting system to compatible AR-15 rifles. The aluminum rail uses M-LOK slots for modular accessories and a continuous top Picatinny section for sights and other 1913-mounted equipment. Its slim profile gives the support hand a relatively narrow gripping surface compared with a full quad rail.

BCM uses a proprietary barrel-nut and lock-up system designed to keep the handguard indexed to the upper receiver while isolating it from barrel contact. The 13 in configuration offers substantial front-end coverage without extending as far as the 15 in version. Browse more gun parts and accessories for related AR-15 rails and compatible components.

The MCMR-13 should be matched to the barrel, gas system, muzzle device, and low-profile gas block before installation. Accessory placement can then be tailored with M-LOK sections rather than relying on fixed rail on every side. After assembly, confirm handguard alignment and hardware torque before attaching any optic, laser, or other device that depends on the rail holding its position.
