Faxon Firearms 18" GUNNER 5.56 NATO Rifle-Length 4150 Nitride / Melonite Barrel

Faxon Firearms 18" GUNNER 5.56 NATO Rifle-Length 4150 Nitride / Melonite BarrelThe Gunner profile is a blend of two of the best-performing profiles of all time, Gov't and Pencil.Proving that every once in a while, the Government can do something right, the Gunner's profile from the extension to the gas block mimics that well-known taper. From there, innovation takes over, and the Gunner moves to a .625" gas block journal and our famed pencil profile out front.Removing the weight from the front of the barrel ensures maximum versatility and keeps material to the rear, maximizing heat resistance and mitigating whip.Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle to grave, these barrels are fully stress-relieved, air-gauge tested, and 11-degree target-crowned to ensure superior accuracy.Quality is imbued into our barrels from the start. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel undergoes a battery of tests at each operation until it is finished in Nitride, and is finally inspected. All barrels are individually checked for headspace using precision, custom-hardened gauges.Specifications Barrel Type: Button Rifled Barrel Caliber: 5.56 NATO Barrel Twist: 1:8 Barrel Length: 18" Barrel Profile: GUNNER Light Hybrid Barrel Gas System: Rifle Length Inside Finish: QPQ Nitride Outside Finish: QPQ Nitride Muzzle Thread: 1/2-28 TPI (Threads Per Inch) Gas Block Diameter: .625" Gas Block Journal Length: 1.9" Barrel Extension: M4 Weight: 1.58 lbs Magnetic Particle Inspected 11-degree Target Crown
