Sleek and Reliable Lightweight BCG For 5.56 Gunner Rifles
The Faxon Firearms 5.56 Gunner Lightweight Bolt Carrier Group is an outstanding option for AR-15 builders running the .223/5.56 caliber platform. It offers the lightest weight possible for a BCG capable to live up to the Gunner name without compromising its strength and function.
The Gunner BCG is designed with lightening cuts that significantly reduce the overall weight of the rifle. All parts were coated with Salt Bath Nitride finish that increases the carrier’s natural slickness requiring less gas and pressure to operate. The Nitride process also seals the BCG components against corrosion while also making them fantastically wear-resistant.
Shot-Peened & MPI Tested
The Faxon Firearms 5.56 Gunner Lightweight Bolt Carrier Group is made from 9310 tool steel, shot-peened, and magnetic particle inspected to military specifications for the highest quality ensuring no hidden cracks or stress points that may compromise safety.
Its bolt lugs are also chamfered to ensure reliable action for high-pressure hand loads and fast lightweight actions. Gas keys use grade 8 fasteners and are fully staked while the extractor is made from S7 steel, which is optimal for resisting the shock of pulling cartridges out of the chamber when firing.
NOTE: Faxon recommends the use of an adjustable gas block with the lightweight BCG for proper function.
