Wilson Combat TRBCANB308 Bolt Carrier Assembly 308 DPMS AR-10 Nickel Boron

The Wilson Combat TRBCANB308 Bolt Carrier Assembly is a precision-machined .308 Winchester bolt carrier group purpose-built for any DPMS-pattern AR-10 platform rifle. Designed as a drop-in BCG for the big-bore AR, it is engineered to the same exacting standards Wilson Combat applies across its 308 AR parts line.

The carrier is machined from hardened steel and finished in a polished Nickel Boron coating. This low-friction, self-lubricating surface promotes smoother cycling, added corrosion resistance, and easy carbon wipe-off during routine cleaning. The bolt assembly uses a precision-machined steel bolt with a hardened S7 tool steel extractor, giving the BCG the strength and durability needed for sustained .308 Win use.

Whether you are assembling a new hunting, defensive, or general-purpose .308 AR-10 or replacing a worn carrier in an existing build, this bolt carrier assembly delivers the smooth operation and long-term reliability expected from a premium American-made component.
