Faxon Firearms TiN M16 Bolt Carrier Group
The Faxon Firearms TiN M16 Bolt Carrier Group is built for shooters who expect more than standard Mil-Spec performance. Faxon starts with proven materials and enhances the design with upgraded components, including a stronger 9310 tool steel bolt, superfinished carrier surfaces, and salt bath nitrided components for increased hardness, reduced friction, and improved corrosion resistance. Finished with a gold TiN PVD coating on the carrier assembly, this BCG delivers smooth operation, easier cleaning, and a distinctive appearance.
Designed for reliability under demanding conditions, each bolt is heat-treated, shot-peened, and magnetic particle inspected to ensure material integrity. The M16 full-auto profile carrier is compatible with full-auto fire control groups and modern multi-stage trigger systems, while the properly staked gas key and durable extractor assembly provide long-term dependability.
