The Faxon Firearms FX7 Bolt Action Prefit Barrel, 308 Win 22-inch M24 Contour, Nitride (Faxon part no. 7F1B810N22N24Q) is a precision-oriented bolt-action barrel built for shooters assembling or rebarreling a 308 Winchester bolt gun. Faxon Firearms cuts it in the M24 contour, a medium-heavy sniper-pattern profile popularized by military designated-marksman rifles, giving it the mass to hold zero through long strings of fire. It’s part of Faxon’s FX7 prefit line, machined and chambered to close tolerance for a straightforward barrel swap on a compatible action. A 1-10 twist rate covers the common range of .308-class bullet weights, and a QPQ nitride finish protects the bore and exterior against corrosion and wear.
