Description

The Bravo Company (BCM) MCMR-15 is a free-float modular rail designed to bring M-LOK accessory compatibility and a proven barrel-nut lockup to AR-platform rifles. Machined from aerospace-grade 6061-T6 aluminum and finished with a hard coat anodize, the MCMR-15 provides a lightweight, rigid mounting surface while positioning hardware to reduce the effects of heat-induced movement.
