Faxon's Match Series 16" Gunner Profile .223 Wylde barrel is designed for shooters who want a lightweight, fast-handling rifle without sacrificing precision or durability. The Gunner contour blends government-profile strength through the extension with a pencil-like forward taper, giving the rifle exceptional balance for competition, training, or duty roles. Chambered in .223 Wylde, it delivers match-grade accuracy with .223 Rem while safely handling higher-pressure 5.56 NATO-making it a versatile choice for any AR builder. Crafted from 416R stainless steel and button-rifled with 5R geometry and a 1:8 twist, this barrel offers consistent precision across a wide range of bullet weights. The full nitride treatment-inside and out-adds corrosion resistance, reduces fouling, and extends service life. Faxon's Nickel Teflon-coated M4 extension enhances lubricity and provides a tighter, more consistent lockup with the upper receiver. Each Match Series barrel is stress relieved, air-gauge tested, MPI inspected, and individually headspace-verified for dependable performance right out of the box.
