Faxon Firearms Gunner .338 ARC 14.5" Black Nitride 416-R Stainless AR-15 Barrel

The Faxon Firearms Gunner profile barrel chambered in .338 ARC is a precision-built drop-in upgrade for the AR-15 platform. This 14.5" barrel is machined from 416-R stainless steel and finished in a tough Black Nitride coating for excellent wear and corrosion resistance. The Gunner profile blends the durability of a Government contour near the chamber with the weight savings of a Pencil profile out front, giving shooters a balance of rigidity and quick handling.

Cut with a 1:8 twist and button rifled, this barrel is optimized to stabilize the heavier bullets common to the .338 ARC cartridge, which was designed to deliver substantially more energy than 300 Blackout while fitting standard AR-15 magazines and bolt interfaces. The result is a compact, hard-hitting package well suited to hunters and shooters looking to push the AR-15 beyond traditional calibers.

Whether you are building a hunting rig, a hard-duty carbine, or a specialty upper for suppressed use, this Gunner-profile .338 ARC barrel delivers the accuracy, reliability, and weight balance that Faxon Firearms is known for.
