Faxon 350 Legend 16" Gunner Barrel

Faxon 350 Legend 16″ Gunner Barrel

The Faxon 350 Legend 16″ Gunner Barrel delivers the perfect balance of lightweight maneuverability, superior accuracy, and durability for hunters and AR builders seeking maximum performance from the straight-wall 350 Legend cartridge. Designed for deer hunters, range shooters, and tactical enthusiasts, this barrel’s hybrid Gunner profile provides unmatched balance and heat control in the field.

Machined from 4150 Chrome Moly Vanadium (CMV) steel and treated with a QPQ Nitride finish, the 16″ Gunner resists corrosion, fouling, and barrel wear even under hard use. Each Faxon barrel is 100% manufactured in-house from gun-barrel-quality bar stock and inspected with custom headspace gauges and MPI testing to ensure precision alignment and long service life. The result is a barrel built for accuracy, reliability, and repeatable performance in every shot.

Featuring an M4 feed ramp extension, the Gunner barrel guarantees smooth, reliable feeding across a wide range of hunting and defensive loads—ideal for semi-automatic AR-15 350 Legend builds. Its carbine-length gas system supports consistent cycling and dependable function, while the 0.75″ gas block journal allows broad compatibility with standard AR-15 gas blocks.

At just 16 inches, this barrel excels in dense woods, blinds, and close-quarters hunting setups where quick handling is key. The Gunner profile blends the best attributes of Government and Pencil barrel designs—retaining rear mass for heat absorption and stiffness while reducing front-end weight for superior balance and faster target transitions. The result is a lightweight, precision-ready 350 Legend barrel that handles like a feather but performs like a heavy-contour match barrel.
