Faxon 5.56 Gunner Lightweight Bolt Carrier Group – Nitride with TiN PVD

The Faxon 5.56 Gunner Lightweight Bolt Carrier Group – Nitride with TiN PVD is an ideal upgrade for AR-15 builders seeking reduced reciprocating mass, smoother cycling, and premium aesthetics. Weighing only 8.5 ounces complete, this BCG is perfect for lightweight builds and competitive shooting applications.

The bolt is machined from high-strength 9310 tool steel, shot peened, and MPI tested to ensure exceptional durability. The carrier is made from MIL-SPEC 8620 steel and receives a QPQ Salt Bath Nitride treatment for corrosion resistance and surface hardness. On top of this robust base, Faxon applies a Titanium Nitride (TiN) PVD coating, offering both a bold gold finish and improved lubricity for reduced fouling and wear.

With forward assist serrations and a full-auto rated profile, this BCG ensures reliable function in a variety of AR-15 platforms. It includes a properly staked gas key made from 4140 steel, a cam pin and firing pin of hardened steel, and an S7 tool steel extractor—components chosen for strength and long-term performance.

This bolt carrier group is compatible with .223 Remington, 5.56 NATO, and .300 Blackout builds. When paired with an adjustable gas block, the Faxon Gunner BCG delivers a finely tuned and responsive shooting experience.
