Bootleg 5.56 Nitride BCG Complete – AR-15/M16 Platform

The Bootleg 5.56 Nitride BCG is a complete bolt carrier group engineered for reliable function in AR-15 and M16 platform rifles chambered in 5.56 NATO/.223 Remington. This BCG handles the core cycle of operation—feeding, chambering, locking, firing, extraction, and ejection—making it a direct replacement for factory or worn components. Shooters upgrade to aftermarket BCGs for improved surface hardness, easier cleaning, or as a spare to keep their rifle running.

The bolt carrier, bolt, gas key, cam pin, and firing pin are treated with a black nitride finish, which increases surface hardness and corrosion resistance while reducing friction. Nitride penetrates the metal rather than coating the surface, resulting in a finish that won't flake or chip. The gas key is properly staked per mil-spec standards. This is a drop-in component for standard AR-15 lower and upper receivers—no gunsmithing required, though basic familiarity with AR-15 disassembly is recommended for installation.
