This Faxon Firearms barrel (Faxon part number 15B338A8P145NGQ-5R-NP3) is chambered in .338 ARC and built in the brand’s Gunner profile, machined from 416-R stainless steel and finished in black nitride. The Gunner profile combines the durability of a Government profile with the weight savings and maneuverability of a Pencil profile, shifting the rifle’s balance back toward the shooter’s body to limit fatigue during long days of shooting, training, or hunting. At 14.5 inches with a 1:8 twist, it ships without sights, ready to build into a lightweight, well-balanced AR-15 upper.
