Each barrel is button rifled and individually checked for headspace using precision gauges, then final inspected to help ensure reliable fit and function. The Big Gunner profile balances handling and stiffness, while the carbine-length gas system, 11-degree target crown, and M18x1.5 muzzle threads (with tapered shoulder) make it a strong option for practical accuracy-focused and suppressor-ready configurations (verify alignment and compatibility before use).\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e4150 CMV \/ mil-spec steel construction for strength and heat tolerance in demanding use\u003c\/li\u003e\n  \u003cli\u003eSalt bath nitride (QPQ) inside and out to resist corrosion and reduce fouling\u003c\/li\u003e\n  \u003cli\u003eBig Gunner profile designed to balance weight, rigidity, and repeatable performance\u003c\/li\u003e\n  \u003cli\u003eCarbine-length gas system with 1.9\" gas block journal length for AR-10 builds\u003c\/li\u003e\n  \u003cli\u003e11° target crown and M18x1.5 threaded muzzle with tapered shoulder for consistent muzzle performance\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 10A863C16NGQ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 816341026384\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 8.6 Blackout (8.6 BLK)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 16\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfile:\u003c\/strong\u003e Big Gunner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRifling:\u003c\/strong\u003e Button rifled\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\u003eFinish:\u003c\/strong\u003e Salt bath nitride (QPQ), inside and outside\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Carbine-length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block Diameter:\u003c\/strong\u003e 0.875\" (journal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block Journal Length:\u003c\/strong\u003e 1.9\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Threads:\u003c\/strong\u003e M18x1.5 (tapered shoulder)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e 11° target crown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.2 lb\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.
