Featuring a case-hardened 8620 billet steel carrier, the Battle Arms Development AR-15 / M16 Full Auto Enhanced Bolt Carrier Group is the ultimate BCG for any AR rifle build. Finished with a laser-engraved Battle Arms Development (BAD Inc.) logo, this carrier group includes a 17-4 H-900 center-ground steel firing pin, a 4140 steel gas key with 8 properly staked screws, a 4140 hardened steel cam pin, 9130 shot-peened steel bolt, and a 4140 billet steel extractor for exceptional service and consistent performance under semi-auto or full-auto fire. Boasts an ultra-hard and corrosion-resistant black nitride top surface layer for optimal wear resistance and superior lubricity. Plus, the enhanced carrier geometry reduces carrier tilt, and the key bearing surfaces are relocated for increased reliability.
