Each barrel is machined from 4150 steel bar stock, fully stress-relieved, air-gauge tested, and Magnetic Particle Inspected (MPI) to help ensure consistency and reliability. An 11-degree target crown supports precise shot-to-shot performance, while the pistol-length gas system and Big Gunner profile make this a compact, purpose-built option for 8.6 BLK builds. A salt bath nitride treatment is applied inside and out for enhanced corrosion resistance and wear performance, with a black oxide barrel extension for a clean, durable finish.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003ePurpose-built 12-inch 8.6 Blackout barrel developed with Q to maximize the cartridge’s performance\u003c\/li\u003e\n  \u003cli\u003eQuality-control focused build: stress-relieved, air-gauge tested, and MPI inspected\u003c\/li\u003e\n  \u003cli\u003e11-degree target crown for improved accuracy potential\u003c\/li\u003e\n  \u003cli\u003eSalt bath nitride inside\/out for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eAR-10 compatible DPMS Gen 1 .308 extension with M18x1.5 threading and tapered shoulder (adapter included)\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 A0A863P12NGQ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 816341026377\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 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfile:\u003c\/strong\u003e Big Gunner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Pistol\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRifling:\u003c\/strong\u003e Button rifled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e 11-degree target crown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 4150 steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Salt Bath Nitride (inside\/outside); Black Oxide barrel extension\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Threads:\u003c\/strong\u003e M18x1.5 with tapered shoulder (adapter included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block Journal:\u003c\/strong\u003e 1.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e AR-10; standard DPMS Gen 1 .308 extension\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:3\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.
