The Q, LLC. Honey Badger Two-Piece Bolt Carrier Group Upgrade Kit is a premium, factory-certified retrofit system engineered specifically for .300 Blackout and 5.56 NATO platforms. This specialized assembly features a durable maraging stainless steel front section finished in a wear-resistant black nitride coating paired with a bare, heat-treated stainless steel rear housing. To optimize reliable cycling and mitigate bolt bounce during rapid operation, the carrier integrates an innovative SCAR-cut design filled with internal tungsten dampening beads. The advanced internal architecture completely eliminates the standard firing pin retaining cotter pin, replacing it with a simplified single-pin retention system for easier toolless field stripping. Weighing approximately 11.7 ounces and measuring 9.10 inches in length, the comprehensive kit ships complete with an updated larger-diameter recoil spring and a new buffer stop assembly. Q, LLC.
