The BCM Gunfighter MCMR 15-inch Handguard (brand part no. BCM-MCMR-15-556-BLK) is a free-float M-LOK rail built for the AR-15 platform. By fully floating the barrel, the MCMR eliminates the loads a clamped handguard can put on the barrel, reducing deflection for more consistent accuracy shot to shot. A steel barrel nut resists movement and warping under heat, and the whole assembly is machined from aluminum and finished in a durable black hard-coat anodizing. At 15 inches, it gives shooters plenty of M-LOK real estate for lights, grips, and other accessories on a mid-length or rifle-length gas system build. Backed by Bravo Company Mfg / BCM‘s reputation for duty-grade AR components, the MCMR is built to hold zero under hard use.
