Faxon Firearms Duty Series AR-15 .350 Legend 20" 1:16 Gunner Profile Barrel - Black Nitride

The Faxon Firearms AR-15 barrel in .350 Legend is a 20-inch button-rifled replacement barrel from the manufacturer's Duty Series, designed for straight-walled hunting and recreational AR-platform builds. Machined from 4150 Certified Gun Barrel Quality steel and finished in black nitride, each barrel is fully stress relieved and air gauge inspected in-house for consistent accuracy shot after shot.

Featuring the Gunner profile - a hybrid contour that balances weight and rigidity for a variety of builds - this barrel uses a 1:16 twist rate optimized for stabilizing .350 Legend projectiles. It is paired with a carbine-length gas system and standard 1/2x28 muzzle threads, making it a direct fit for AR-15 upper receivers chambered in .350 Legend. Each barrel is fully machined in the USA.

This listing is for the barrel only - no bolt carrier group, handguard, upper receiver, or muzzle device is included. Pair this barrel with a compatible .350 Legend bolt, a carbine-length adjustable gas block, and your preferred handguard and muzzle device to complete your build.
