The rifle-length gassystem on an 18-inch barrel delivers a soft impulse and broad tuning flexibility, while the Gunner contour keeps weight and handling in check for practical rifles that still need reach. Duty Series barrels start with 4150 CMV steeland standard button rifling, then receive QPQ salt bath nitride inside and out for strong corrosion resistance and long service life. The Gunner (Big Gunner) profile uses a sturdier taper behind the gas block for rigidity and a slimmer forward section to reduce front-end weight—an excellent combination for general-purpose builds and suppressor-ready setups. Proudly American-made by a family-ownedmanufacturer in Greater Cincinnati, Ohio, each barrel is built for consistent performance and backed by the Faxon standard of quality.
