The Faxon AR10 Barrel (brand part no. 10BC8R22FHQ-5R-NP3) is a 22-inch heavy fluted barrel chambered in 6.5 Creedmoor, built by Faxon Firearms for AR10-pattern rifles that need long-range accuracy without carrying a full bull-profile weight penalty. Faxon cuts the barrel with 5R rifling, a rifling geometry known for gentler engagement with the bullet jacket and reduced fouling compared to conventional lands and grooves, then finishes the muzzle with an 11-degree target crown to protect accuracy at the critical point where the bullet leaves the bore. The heavy fluted profile pulls weight out of the barrel while adding surface area for heat dissipation, and the barrel extension carries a nickel Teflon coating for smoother bolt lug engagement. Threaded and set up with a rifle-length gas port and a .750 gas block, this barrel is built for precision rifle shooters and long-range hunters running a 6.5 Creedmoor AR10 build.

Frequently Asked Questions

What does 5R rifling do differently than standard rifling? 5R rifling uses an odd number of lands with angled sides instead of square-cut grooves, which reduces bullet jacket deformation and tends to foul less than conventional rifling.

Does the fluting reduce the barrel’s rigidity? Faxon engineers the flute depth and pattern to remove weight and add cooling surface area while keeping the barrel stiff enough for consistent accuracy.

Is this barrel threaded for a muzzle device? Yes, it ships threaded and ready for a compensator, brake, or suppressor mount.
