Faxon Gunner Lightweight Bolt Carrier Group AR-15 223 Remington, 5.56x45mm

Description

Faxon Gunner Lightweight Bolt Carrier Group AR-15 223 Remington, 5.56x45mm. The Faxon Gunner Lightweight Bolt Carrier Group is Faxon’s lightest possible BCG to date – only 8.5 ounces complete and 6.24 ounces for the carrier and key only. The Gunner is “super finished” to reduce friction,and  fouling, and increasethe  smoothness of operation. The BCGs are full-Auto rated and maintain the trip for full-auto fire control groups and new multi-stage trigger systems. Gas keys use grade 8 fasteners and are fully staked for a lifetime of service. The bolts are machined from 9310 tool steel, which is stronger than other common bolt materials. The bolt is also nitrided which increases the surface hardness, decreases resistance, and has superior corrosion resistance compared to typical chrome andphosphated bolt carrier groups. The bolt is fully MPI tested to ensure the material is sound and without defects. Bolt lugs are chamfered 45 degrees to ensure reliable action for even the highest pressure hand loads and fast lightweight actions. The extractor is made from S7 tool steel, fully heat-treated, shot peened per MIL-SPEC, and QPQ nitrided. The Extractor is sprung using the spring, o-ring, and silicone insert.
