Faxon’s Gunner contour blends the strength of a Government profile with the weight savings and fast handling of a Pencil profile, shifting the rifle’s balance back toward the shooter for reduced fatigue during long training days, competition, or hunting. Manufactured in-house in Cincinnati, Ohio, each barrel is stress relieved, air-gauge tested, and finished with a corrosion-resistant black nitride treatment inside and out. A button-rifled 1:8 twist and 11-degree target crown help deliver consistent accuracy, while final inspection and headspace verification support dependable function.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eGunner profile contour blends Government-strength rigidity with Pencil-profile maneuverability for an excellent balance point.\u003c\/li\u003e\n  \u003cli\u003e20-inch 5.56 NATO chamber with 1:8 twist rate helps stabilize a wide range of common bullet weights for practical accuracy.\u003c\/li\u003e\n  \u003cli\u003eBlack nitride finish inside and out improves corrosion resistance and makes cleaning easier after high round counts.\u003c\/li\u003e\n  \u003cli\u003eRifle-length gas system supports a smoother recoil impulse and reliable cycling in full-length AR-15 setups.\u003c\/li\u003e\n  \u003cli\u003eMade in the USA with stress relief, air-gauge testing, and headspace checks for quality control and consistency.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Faxon Firearms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 15A58R20NGQ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 816341020214\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 5.56 NATO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 20 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Profile:\u003c\/strong\u003e Gunner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 4150 CMV (chrome-moly-vanadium) steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRifling:\u003c\/strong\u003e Button rifled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Rifle length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish (Inside\/Outside):\u003c\/strong\u003e Nitride\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Thread:\u003c\/strong\u003e 1\/2-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block Diameter:\u003c\/strong\u003e 0.625 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block Journal Length:\u003c\/strong\u003e 1.9 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Extension:\u003c\/strong\u003e M4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e 11-degree target crown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.67 lb (approx.)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e USA (Cincinnati, Ohio)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
