Faxon 458 SOCOM Nitride Bolt Carrier Group

The Faxon 458 SOCOM Nitride Bolt Carrier Group is engineered for enhanced reliability and long-lasting durability. This full-auto rated BCG is compatible with full-auto fire control groups and modern multi-stage trigger systems, offering exceptional performance for heavy-duty use. Manufactured in-house using premium U.S.-sourced materials, this BCG is Magnetic Particle Inspected (MPI) to ensure structural integrity under high-stress conditions.

Its Black Nitride finish significantly increases surface hardness, improves corrosion resistance, and reduces overall wear—ideal for handling high-pressure hand loads and fast-action builds. Faxon goes a step further with their “Super Finish” process, which minimizes friction and fouling, ensuring smooth cycling and extended maintenance intervals.

Designed with 45-degree chamfered bolt lugs for improved cycling reliability and an S7 tool steel extractor, this BCG is built for shooters who demand the best. Whether you’re upgrading an existing rifle or completing a new build, the Faxon 458 SOCOM BCG provides a performance-driven solution that pairs perfectly with Faxon’s lineup of barrels and AR components.
