Faxon AR10 Barrel, 6.5 Creedmoor, 20 Inch, 1:8 5R Heavy Fluted, Black

The Faxon AR10 Barrel, 6.5 Creedmoor, 20 Inch, 1:8 5R Heavy Fluted, Black (Faxon part number 10BC8R20FHQ-5R-NP3) is built for AR-10 shooters who want long-range precision without sacrificing durability. Faxon cuts this barrel to a 1:8 twist to stabilize the heavier, high-BC bullets favored in 6.5 Creedmoor long-range and hunting loads, and rifles it with a 5R hybrid rifling pattern that reduces bullet jacket deformation for better accuracy. The heavy fluted profile trims weight compared to a straight heavy-contour barrel while retaining the mass needed for barrel life and heat management, finished with an 11-degree target crown to protect accuracy at the muzzle. A rifle-length gas port and .750 gas block size round out a barrel built for a serious precision AR-10 build.
