Bolts & Carrier Groups

AR-15, AR-10 & PCC Bolt Carrier Groups

Faxon Superfinished bolt carrier groups pair an 8620 steel carrier with a 9310 steel bolt that is high-pressure tested (HPT), magnetic particle inspected (MPI) and shot peened, add an S7 extractor and a gas key held by grade 8 fasteners and fully staked, then finish in salt bath nitride, PVD or hard chrome. Made in the USA. Every Faxon AR-15 BCG is an M16-pattern, full-auto rated carrier that works with forced reset triggers (FRTs) and super safeties that don’t require modifying the carrier. Faxon 9mm and 10mm PCC carriers work with most FRTs once the removable weight is taken out.
