Faxon Firearms FX7 Prefit Barrel Features The Faxon Firearms Prefit barrel is engineered to fit and function seamlessly with the FX7 bolt action receiver eliminating the guesswork of matching a tenon and headspace to a new action. Machined from 416R stainless steel the barrel uses 5R button rifling that is honed and lapped for a smooth accurate bore. The 1:10 twist rate is well suited to a wide range of .308 Winchester bullet weights giving shooters flexibility in load selection. A magnetic particle inspection process checks the barrel for internal flaws before it leaves the factory and a recessed target crown protects the muzzle from damage. Finished in Salt Bath Nitride this barrel resists corrosion and wear from repeated range sessions and field use in all weather conditions. The Gunner contour profile balances weight and stiffness for a barrel that handles well off a bipod or bag without becoming unwieldy to carry. Threaded 5/8x24 at the muzzle it accepts a brake or suppressor for shooters who want to manage recoil or reduce noise signature. At 18 long and 2.16 lbs this Faxon Firearms Prefit barrel is a direct upgrade path for anyone running an FX7 action who wants a precision .308 Winchester barrel built to exact tolerances.
