The BCM MK12 MOD-0 5.56 NATO Rifle in black (BCM part no. 862-MK12-BLK) recreates the Mk 12 Special Purpose Rifle pattern favored by military special operations units, built for the civilian market by Bravo Company Mfg / BCM. It pairs an 18-inch barrel with a rifle-length gas system for a smoother, softer cycling impulse than a standard carbine-length gun, topped with a PRI Gen III 12-inch carbon fiber free-float handguard that keeps weight down without sacrificing rigidity. A BCM Mod 4 pistol grip, BCM Mk2 charging handle, and an HPT/MPI-tested BCM bolt carrier group round out BCM’s reputation for reliability, while the AE MK12 compensator helps keep the muzzle flat under rapid fire. Built for precision-minded shooters, designated marksman training, or anyone who wants genuine special-operations pedigree in a semi-automatic rifle, this MK12 MOD-0 delivers.
