The Spike’s Tactical Phosphate Bolt Carrier Group (BCG) is a proven, duty-grade component designed for reliability, durability, and consistent performance in AR-15 platforms. As one of the most critical parts of your rifle, this BCG is built to the same standards used in Spike’s Tactical factory builds—ensuring dependable function when it matters most.

Manufactured from high-quality materials and finished in a classic phosphate coating, this bolt carrier group offers excellent wear resistance and long service life. The phosphate finish retains lubrication well, helping reduce friction and maintain smooth cycling under demanding conditions.

Engineered to meet or exceed mil-spec standards, this BCG is designed for proper gas system function, reliable extraction, and consistent feeding. Whether you're building a new rifle or upgrading an existing setup, this bolt carrier group provides the durability and performance serious shooters expect.

Ideal for duty rifles, range builds, or defensive applications, the Spike’s Tactical Phosphate BCG delivers trusted reliability without compromise.
