The BCM KMR Alpha handguard (BCM part number BCM-KMR-A13-556-BLK) is a 13-inch free-floating Keymod rail built from aluminum with a hardcoat anodized finish for corrosion resistance. Bravo Company Mfg engineered its interface system to work alongside the standard Picatinny system, giving builders four offset mounting positions between the traditional 3, 6, 9, and 12 o’clock positions for extra modularity. It ships complete with a BCM Keymod sling mount, finished in black for a durable AR-15 build.
