BCM MCMR M-LOK - Free Float Handguard - 15"

The Bravo Company MCMR 15-inch free float handguard gives precision-oriented AR-15 builds an extended barrel-free platform that improves accuracy, supports forward accessory placement, and uses BCM's proven patented mounting system to keep everything stable under heat and sustained fire.

The BCM MCMR is a 15-inch free float M-LOK AR-15 handguard built from 6061-T6 aluminum alloy with BCM's proprietary patented barrel nut system for a heat-stable, mechanically indexed lockup.

The 15-inch length gives your support hand more reach forward of the gas block, improving leverage and reducing muzzle rise during rapid-fire strings — a meaningful ergonomic advantage on a full-length precision or competition build. BCM's patented mounting system mechanically indexes to the 12 o'clock rail, so the handguard reinstalls in exact alignment every time after maintenance. Mounting hardware placement is engineered to resist the movement that heat cycling generates, keeping accessories zeroed across temperature variations and high-round-count sessions. Note: the listed 15-inch length refers to the top Picatinny rail section; the actual handguard body is slightly longer.

Compatible with standard AR-15 upper receivers. Finished to MIL-A-8625F, Type III, Class 2 anodize standard. Inside diameter 1.3 inches, width 1.5 inches. Steel barrel nut included.

6061-T6 aluminum alloy with MIL-A-8625F Type III Class 2 hardcoat anodize. The same material and finish spec as the full BCM MCMR lineup.

The right choice for long-range AR-15 builds, precision competition setups, and duty rifles where a longer rail platform improves ergonomics and stability under real-world operating conditions.

Bravo Company Manufacturing builds AR-15 components and rifles to a standard that exceeds mil-spec minimums. Their products are trusted by professional end users who depend on equipment that performs consistently.
