BCM MCMR 3" M-LOK Picatinny Rail Section Polymer Black

The BCM MCMR 3" Picatinny Rail Section is a lightweight, one-piece accessory mount from Bravo Company Manufacturing designed to drop onto any M-LOK compatible handguard. Cut from impact-resistant polymer, this 3-inch section provides 5 slots of true MIL-STD 1913 Picatinny real estate for clamping on red dots, backup iron sights, lights, lasers, or other mission accessories without piling weight on the front end of your rifle.

Built to original Picatinny arsenal specifications, the BCM rail section features the correct recoil-lug slots and slot spacing so standard 1913 rings and clamps seat solidly and lock down with no play. A snag-resistant profile keeps the rail from grabbing on slings, plate carriers, or brush, and the durable polymer shrugs off impacts, weather, and hard field use. The black finish blends cleanly with most factory and aftermarket handguards for a low-visibility look.

Designed and made in the USA by Bravo Company Manufacturing, this section is optimized for BCM's own KMR-A and MCMR series handguards and fits any standard M-LOK slot pattern. It attaches via the standard M-LOK interface and can be removed or repositioned along the handguard to suit your preferred optic, light, or laser placement - no permanent modification required.
