The Faxon 5.56 M16 Bolt Carrier Group is a high-performance and reliable upgrade for your AR-15. Designed for optimal performance and made with top-quality materials, ensuring durability and longevity. The nitride finish on the carrier and bolt provides added corrosion resistance, making it a great choice for use in harsh environmental conditions. Features a full-auto design making it compatible with M16-style rifles and other firearms that use a similar operating system. The enhanced design of the bolt carrier group provides smooth and consistent cycling, resulting in reliable and accurate performance. Improvements over Mil-Spec bolt carriers include using 9310 tool steel for the bolt, nitriding the assembly to increase surface hardness, decrease resistance, and have superior corrosion resistance compared to typical chrome and phosphasted bolt carrier groups. All bolts are 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. Gas keys use grade 8 fasteners and are fully staked for a lifetime of service.
