The DPMS Panther Arms DP51655109766 Bolt Carrier Group 5.56/300BO Phosphate Steel is a mil-spec, full-auto rated BCG built around a Carpenter 158 steel bolt for dependable performance in AR-15 platforms. The carrier features a durable manganese phosphate finish on the outside with a chrome-lined interior, while the chrome-lined gas key is machined from bar stock and secured with grade 8 fasteners that are properly staked to military specifications.

This bolt carrier group is designed for use with 5.56 NATO, .223 Remington, and .300 AAC Blackout, making it a versatile choice for range use, training, and general-purpose rifles. Each bolt is shot peened, high-pressure tested, and magnetic particle inspected to help ensure long-term reliability. Packed dry from the factory, the BCG may appear gray and dusty at first but quickly darkens when lubricated, reflecting DPMS Panther Arms’ focus on practical, hard-use components and consistent craftsmanship.
