Faxon Gunner Lightweight 5.56x45mm BCG, 9310 Steel, Nitride

Description

The Faxon Gunner Lightweight Bolt Carrier Group is a mil-spec complete BCG intended for use in AR-15 style rifles chambered in 5.56x45mm NATO. The carrier and bolt are produced from high-strength 9310 steel, and the carrier components receive a salt bath nitride finish for enhanced surface hardness and corrosion resistance. The Gunner Lightweight geometry reduces carrier mass and uses an enhanced cam path designed for smoother cycling while maintaining compatibility with mil-spec controls and accessories. Forward assist serrations and dust cover compatibility are included in the design.
