FAXON DUTY SERIES GUNNER PROFILE 16" CARBINE-LENGTH 400 LEGEND AR15 BARREL
The Faxon Duty Series 16" 400 Legend AR Barrel brings Faxon’s proven Gunner profile to the next evolution of straight-wall hunting cartridges. The .400 Legend offers excellent energy transfer and reduced recoil—perfect for deer hunting in straight-wall states.
The Gunner profile combines the durability of the Gov’t profile with the weight savings of a Pencil barrel, maintaining rifle balance and reducing fatigue for long sessions in the field or at the range.
Each barrel is fully stress relieved, air-gauge tested, and 11° target crowned for superb accuracy and durability. Made from 4150 CMV steel and Nitride treated inside and out, these barrels are built to perform for a lifetime.
