Featuring Faxon’s Big Gunner contour (medium taper behind the gas block with a slimmer forward taper), this barrel helps reduce front-end weight while maintaining the stability needed for high rates of fire and suppressor-host use. It’s manufactured from duty-grade 4150 CMV steel and finished with salt bath nitride (QPQ) inside and out for excellent wear and corrosion resistance. A rifle-length gas system promotes a smooth recoil impulse, while the 11° target crown and 1:10 twist are optimized for consistent .308 Win performance.\u003c\/p\u003e\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eBig Gunner (Gunner) profile balances strength behind the gas block with reduced forward weight for faster handling.\u003c\/li\u003e\n  \u003cli\u003e4150 CMV steel construction with salt bath nitride (QPQ) inside and out for long-lasting corrosion and wear resistance.\u003c\/li\u003e\n  \u003cli\u003eRifle-length gas system on an 18-inch .308 barrel for a smooth recoil impulse and reliable cycling.\u003c\/li\u003e\n  \u003cli\u003eDPMS \/ LR-308 compatible extension with 5\/8x24 muzzle threads for common .30-cal muzzle devices and suppressor mounts.\u003c\/li\u003e\n  \u003cli\u003eQuality-focused build features include MPI inspection and an 11° non-recessed target crown for consistent shot release.\u003c\/li\u003e\n\u003c\/ul\u003e\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 10A810R18NGQ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 816341023284\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 18 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfile:\u003c\/strong\u003e Gunner (Big Gunner)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwist Rate:\u003c\/strong\u003e 1:10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 4150 CMV steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRifling:\u003c\/strong\u003e Standard button rifled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Salt Bath Nitride (QPQ), inside \u0026amp; out\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Rifle-length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Block Journal Diameter:\u003c\/strong\u003e 0.750 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\u003eMuzzle Threads:\u003c\/strong\u003e 5\/8x24 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Extension:\u003c\/strong\u003e DPMS \/ LR-308 compatible (black oxide)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e 11° target crown (non-recessed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInspection:\u003c\/strong\u003e Magnetic Particle Inspected (MPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.13 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e USA\u003c\/li\u003e\n\u003c\/ul\u003e\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.
