Accurate and Durable Faxon GUNNER 5.56/.223 AR-15 Barrel

The Gunner profile is a blend of two of the best performing profiles of all time, Government and Pencil. Removing the weight from the front of the barrel ensures maximum versatility as well as keeps material to the rear to maximize heat-resistance and mitigate whip.

Proving that every once and awhile, 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 their famed pencil profile out front.

This 16-inch barrel features a 1:8 twist rate for proper projectile stabilization and has 1/2"x28 thread pitch for attaching muzzle devices. It is chambered in 5.56 NATO and also accepts .223 Remington cartridges. The button rifling provides superior accuracy and enhanced barrel life.

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 have an 11-degree target crown to ensure superior accuracy.

Quality is imbued into Faxon barrels from the start. Faxon starts with the best materials, either certified 4150 Mil-Spec steel or 416-R stainless. From there, each barrel goes through a battery of tests at each operation until finished in Nitride and finally inspected. All barrels are individually checked for headspace by precision custom-hardened gauges.
