Faxon Firearms barrels represent the epitome of precision engineering and exceptional value, crafted entirely in-house to ensure unmatched quality from inception to completion. Each barrel undergoes a meticulous manufacturing process, beginning with the selection of premium materials such as certified 4150 mil-spec steel or 416-R stainless. These materials are transformed through a series of rigorous tests, including full stress relief, air Gauge testing and an 11 degree target crown, all designed to deliver superior accuracy. The commitment to excellence is further exemplified in Faxon's MATCH series barrels, which elevate performance standards to new heights. Starting with gun-barrel-quality 416-R bar stock, these barrels feature 5R rifling - a hybrid design that positions lands opposite grooves and minimizes sharp angles. This innovative rifling reduces jacket deformation, enhances velocity and simplifies cleaning. The .223 Wylde chamber, a hybrid configuration, maximizes the benefits of 5R rifling by reducing bullet jump and improving accuracy, while each barrel is individually MPI tested to ensure safety. After passing through stringent quality checks, the barrels receive a nitride treatment both inside and out, enhancing barrel life and providing robust protection against environmental elements. The extension is coated with Nickel Teflon, offering exceptional dry lubricity and corrosion resistance, while also tightening the fit between the extension and receiver to further boost accuracy. The Faxon MATCH series barrels are engineered for those who demand the highest performance, whether in critical duty situations or competitive environments. With their unparalleled combination of precision, durability and value, these barrels are ready to deliver when it matters most. 11 degree recessed target crown Twist rate - 1:8 Gas block diameter - 3/4 inches 1.1 gas block journal length M4 - nickel teflon coated barrel extension Mid-length, 5R rifled, heavy fluted barrel
