The Faxon Superfinished 5.56 Gunner Lightweight Bolt Carrier Group – TiN 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 duty-grade functionality: 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 the bolt and carrier to increase surface hardness, reduce resistance, and provide excellent corrosion resistance. To take performance and wear resistance a step further, this model adds a TiN PVD coated carrier & gas key—a high-performance coating known for durability and a distinctive gold 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.

Frequently Asked Questions
Is this bolt carrier group full-auto compatible?
Yes. This is an M16-pattern carrier that maintains the full-auto trip sear and is compatible with full-auto fire control groups and many modern multi-stage triggers.
Why does a lightweight BCG often require an adjustable gas block?
Reduced-mass carriers typically require less gas to cycle efficiently. An adjustable gas block allows you to tune gas flow for reliability, recoil control, and component longevity—especially when changing ammo or running suppressed.
What is TiN PVD and why choose it?
TiN PVD (Titanium Nitride Physical Vapor Deposition) is applied to the carrier and gas key for enhanced wear resistance and a distinctive finish while maintaining smooth operation.

FAXON 5.56 GUNNER LIGHTWEIGHT 9310 BOLT CARRIER COMPLETE - NITRIDE- TIN PVD
Looks great in your AR. Gives it that pop and sets your gun apart from the rest. The low mass helps with felt recoil and I would suggest also using an adjustable gas bloc to super tune it.

Faxon 5,56 Gunner Lightweight 9310 BCG Nitride TIN PVD
This bolt is great. Operates smoothly and the Tin coating acts as a good lube in conjunction with a small amount. Adding a adj gas block with it because it doesn't need as much gas Oh and did I mention it looks fantastic

You pay what you get
I was doing my year end built and wanted the gold touch and I went for the Faxon TiN lightweight BCG and after the first 200 rds with no adjustable gas block it didn't fail. The whole building has been a success. I do recommend it

Greatness
I purchased this for my 7.5 inch faxon Gunner barrel in 5.56. It runs very well in my upper. Definitely worth getting
