Faxon Superfinished 5.56 Gunner Lightweight Bolt Carrier Group – Chameleon PVD

The Faxon Superfinished 5.56 Gunner Lightweight Bolt Carrier Group – Chameleon PVD is a premium reduced-mass BCG engineered to deliver fast, smooth cycling without compromising strength or reliability. When we evaluated the lightweight BCG market, we saw a capability gap—so we built a carrier that could live up to the Gunner name with no compromises.

The design target was simple: the lightest weight possible—8.5 ounces complete—while retaining critical functionality including forward assist serrations, compatibility with dust covers, and an M16 pattern carrier that maintains the full-auto trip sear for full-auto and many modern multi-stage trigger systems.

Matching our barrels, we selected salt bath nitride for all carrier components to increase surface hardness, reduce resistance, and provide excellent corrosion resistance. This model adds a durable Chameleon PVD coated carrier & gas key for enhanced wear resistance and a unique color-shifting finish.

Faxon Bolt Carrier Groups are Superfinished to reduce friction, increase smoothness of operation, and reduce fouling. Gas keys use grade 8 fasteners and are fully staked for long-term service. After passing all quality inspections, carriers are laser-engraved with the Faxon Shield.

Faxon recommends the use of an adjustable gas block with our Gunner Lightweight BCG for proper function and optimal tuning.

DISCLAIMER: Chameleon PVD coloration will vary. No two Chameleon PVD products have the exact same coloring due to the nature of the coating process.
