Faxon's Match series barrels take our renowned performance and value to the next level. Crafted in house from gun barrel quality 416R stainless steel, each barrel features 5R rifling, a hybrid design that reduces sharp angles, minimizes jacket deformation and increases velocity. The result is better accuracy, faster cleaning and enhanced overall performance. After undergoing rigorous testing, the barrels are nitride treated inside and out, locking in the bore, extending barrel life and providing exceptional resistance to the elements. The Nickel Teflon coated extension further enhances dry lubricity and corrosion resistance, while also improving the fit between the extension and receiver boosting accuracy even more. With the Faxon Match series barrels, you get a barrel that is ready for action whether duty calls or the buzzer beeps, offering unmatched performance and outstanding value.
