Faxon's Match Series barrels are built for shooters who demand superior accuracy, durability, and reliability. Manufactured 100% in-house from gun-barrel-grade 416-R stainless bar stock, each Match Series barrel features 5R rifling-a hybrid profile with reduced sharp angles and lands opposite grooves for improved velocity, less bullet deformation, and easier cleaning. Chambered in .223 Wylde, the Match Series blends the best characteristics of .223 Remington and 5.56 NATO, minimizing bullet jump while maximizing performance with both calibers. Every barrel is MPI-tested to ensure structural integrity under demanding conditions. Further enhancing reliability and fit, the barrel extension is coated in Nickel Teflon, offering dry lubricity and corrosion resistance, while tightening the lock-up between the barrel and receiver for improved accuracy. Faxon Firearms barrels represent the pinnacle of performance and value in the firearms industry. Built entirely in-house from start to finish, each barrel undergoes rigorous quality control measures, including full stress relief, air-gauge testing, and an 11-degree target crown-all designed to maximize accuracy and consistency. Crafted from premium materials such as certified 4150 Mil-Spec steel or 416-R stainless steel, every barrel is subjected to stringent quality assurance checks at every stage of production. Final finishing includes a corrosion-resistant Nitride treatment inside and out, and each barrel is individually headspace-checked with precision-hardened gauges to ensure optimal safety and function.
