Description
If you're building or upgrading a rifle in the Grendel or ARC family, the bolt carrier group is where you don't want to cut corners. Faxon treats mil-spec as a floor, not a ceiling, and this Type 2 BCG shows it. The .136 inch bolt is machined from 9310 tool steel, then heat treated, shot peened, and magnetic particle inspected so you know the metal underneath is sound and free of hidden cracks or stress points. The whole assembly gets a salt bath nitride finish that boosts surface hardness and shrugs off corrosion far better than the older chrome or phosphate coatings you'll find on budget carriers.
What Sets This Faxon Type 2 BCG Apart
The details are where Faxon earns its reputation. The carrier body is superfinished, which knocks down surface roughness so the group cycles smoother and sheds fouling instead of holding onto it. The bolt lugs are chamfered at 45 degrees to help feeding and lockup stay reliable even with hot hand loads and lighter, faster actions. You also get an S7 extractor, a spring insert and crane O-ring already installed, and a gas key fastened with grade 8 hardware that's properly staked to stay put through years of use.
Calibers the Faxon Grendel/ARC BCG Covers
This is a Type 2 group, meaning it uses the .136 inch bolt face that most 6.5 Grendel and ARC-family barrels are cut for. That single bolt handles 6.5 Grendel, 6mm ARC, .22 ARC, and .338 ARC, so it's a versatile pick if you swap uppers or run more than one caliber off the same lower. It's an M16-pattern carrier with forward assist serrations and full-auto compatibility. One thing worth noting before you order: it is not compatible with Faxon 7.62×39 barrels, and it's always smart to confirm your barrel's bolt-face requirement so you're matching the right group to the right barrel.
Real-World Feel of the Faxon Type 2 Bolt Carrier Group
Folks who pair this with a Faxon barrel tend to comment on just how smooth it runs, and the nitride plus superfinish combo makes cleanup a much shorter chore at the bench. It's backed by Faxon's lifetime guarantee against manufacturing and material defects, which is a nice bit of reassurance on a part that does a lot of the heavy lifting in your rifle.

Frequently Asked Questions
What calibers does the Faxon Type 2 BCG work with?
This Type 2 group uses the .136 inch bolt face shared by the Grendel and ARC family, so it covers 6.5 Grendel, 6mm ARC, .22 ARC, and .338 ARC. That makes it a handy choice if you run more than one of these calibers or plan to swap uppers down the road. Just confirm your barrel is cut for the .136 inch bolt before ordering.
Is the Faxon Type 2 BCG full-auto rated?
Yes. It's an M16-pattern carrier that maintains the full-auto trip and works with full-auto fire control groups as well as newer multi-stage trigger systems. It also includes forward assist serrations like a standard M16 carrier.
How is the nitride finish different from a phosphate BCG?
The salt bath nitride treatment increases surface hardness and gives noticeably better corrosion resistance than the older chrome and phosphate finishes. Combined with Faxon's superfinished carrier body, it cuts friction and fouling, so the group cycles smoother and wipes down faster at the cleaning bench.
Will this Faxon BCG work with a 7.62×39 barrel?
No. Faxon specifically notes this Type 2 group is not compatible with their 7.62×39 barrels. It's built for the Grendel and ARC bolt-face family, so match it to a barrel chambered in 6.5 Grendel, 6mm ARC, .22 ARC, or .338 ARC.
