Product Description

The Faxon Firearms Duty Series Gunner barrel is built for AR-15 platforms chambered in 400 Legend (SAAMI), delivering a balanced blend of strength and handling for hunting and range use. Its Gunner profile merges Government-profile durability with Pencil-profile weight savings to help keep the rifle lively and reduce fatigue during extended sessions. Manufactured from 4150 CMV steel with a salt bath nitride finish inside and out, this 16-inch barrel is engineered for long-term corrosion and wear resistance, with a carbine-length gas system for reliable cycling.

Designed around straight-wall performance, it features a Big Bore barrel extension and an 11 degree target crown. Each barrel is stress relieved, air-gauge tested, and headspace verified using PTG gauges to support consistent accuracy and dependable function.
