The Faxon Match Series 14.5" Gunner Profile .223 Wylde Barrel strikes an ideal balance between government-strength durability and pencil-like responsiveness. Designed for shooters who want a fast, agile carbine without sacrificing precision, the Gunner contour shifts weight rearward for quicker transitions, improved balance, and reduced fatigue during extended use. Built from 416R stainless steel with 5R button rifling and a 1:8 twist, the barrel delivers consistent accuracy across a wide range of bullet weights. The .223 Wylde chamber enhances precision with .223 Rem while safely accommodating 5.56 NATO pressures. A full salt bath nitride treatment inside and out provides long-term corrosion resistance and easier maintenance. Faxon's Match Series standards ensure each barrel is stress relieved, air-gauge tested, magnetic particle inspected, and headspace verified. The Nickel Teflon-coated M4 extension improves lubricity and supports reliable feeding and tight receiver fitment. Well-suited for performance AR-15 builds, this 14.5" configuration is also a popular choice for pin-and-weld setups to achieve a 16" legal overall length (verify local laws and muzzle device length).
