Spike's Tactical M16 Bolt Carrier Group – Black Phosphate

The Spike's Tactical M16 Bolt Carrier Group is a mil-spec replacement BCG designed for AR-15 and M16 platform rifles. The full-auto M16 profile carrier provides increased mass over semi-auto BCGs, which helps improve reliability and reduces felt recoil in semi-automatic fire. This BCG is a direct replacement for worn or damaged carriers and serves as a quality spare for shooters who maintain multiple rifles or log high round counts.

Machined from 8620 steel with a black phosphate finish, this carrier group is treated with a properly staked gas key and includes a complete bolt assembly with extractor and ejector. The black phosphate coating provides corrosion resistance and reduces friction for smoother cycling. Installation is drop-in for anyone familiar with AR-15 field stripping—no gunsmithing required.
