Machined from 4150 Chrome Moly Vanadium (CMV) steel and button rifled for consistent, proven accuracy, this 16-inch mid-length barrel delivers a compelling balance of compactness and real-world performance. A full salt bath nitride (QPQ) treatment inside and out provides exceptional corrosion resistance and wear protection, making it equally capable in harsh field conditions or high-round-count training sessions. The Big Gunner profile features a medium taper behind the gas block for strength and rigidity, transitioning to a thinner forward taper to reduce weight and improve handling without sacrificing heat dissipation at sustained rates of fire. With a .750\" gas block journal measuring 1.9\" in length, it is compatible with most standard low-profile gas blocks and aftermarket piston kits. The 5\/8x24 muzzle threading supports a wide range of .30-caliber muzzle devices and suppressor mounts, making this barrel a versatile, suppressor-ready platform. Backed by the Faxon Lifetime Guarantee and proudly manufactured in Greater Cincinnati, Ohio, the Big Gunner is the choice for competition and duty builds where every second counts.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4150 CMV Steel, Button Rifled:\u003c\/strong\u003e Machined from 4150 Chrome Moly Vanadium steel with traditional button rifling for long-lasting accuracy and dependable performance under demanding use.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSalt Bath Nitride (QPQ) Inside and Out:\u003c\/strong\u003e Full QPQ nitride treatment delivers superior corrosion resistance, reduced friction, and enhanced durability for extended service life in any condition.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBig Gunner Profile:\u003c\/strong\u003e Medium taper behind the gas block retains strength and rigidity, while a slimmer forward taper reduces weight for faster target transitions and improved balance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMid-Length Gas System:\u003c\/strong\u003e Optimized dwell time promotes smoother cycling and a more controlled recoil impulse in a 16-inch .308 Win AR-10 build.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e.750\" Gas Block Journal and 5\/8x24 Muzzle Threads:\u003c\/strong\u003e Compatible with most common low-profile gas blocks and piston kits, and supports a full range of .30-caliber muzzle devices and suppressor mounts.\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\u003eCaliber:\u003c\/strong\u003e .308 Winchester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 16\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Profile:\u003c\/strong\u003e Big Gunner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Material:\u003c\/strong\u003e 4150 CMV (Chrome Moly Vanadium) Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Type:\u003c\/strong\u003e Button Rifled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:10 RH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System:\u003c\/strong\u003e Mid-Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block Journal Diameter:\u003c\/strong\u003e .750\"\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\u003eInside Finish:\u003c\/strong\u003e Salt Bath Nitride (QPQ)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Finish:\u003c\/strong\u003e Salt Bath Nitride (QPQ)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMuzzle Thread:\u003c\/strong\u003e 5\/8x24 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e 11 Degree Target Crown (Non-Recessed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlatform Compatibility:\u003c\/strong\u003e LR-308 \/ DPMS Compatible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 816341023260\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 10A810M16NGQ\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.
