FAXON Firearms

Faxon's .308 continue our fantastic barrel-making with a bit more punch. We've updated our previous Medium-Taper profile taking into account customer feedback, optimizing the barrel to meet the Gunner brand's high standards.

The .308 Big Gunner profile barrels are the big-brother to our famous 5.56 Gunner barrels. The Big Gunners feature a medium-taper behind the gas block. The gas block journal is set to .750" for compatibility with most common gas blocks and 1.9" in length for long blocks or aftermarket piston kits. From the gas block journal forward we use a thinner taper, designed to reduce weight yet maintain rigidity for high rates of fire and as a suppressor host.

The Gunner barrels are ideal for any competition or duty use. When the seconds count, count on the Gunner profile.

Faxon's pencil barrels are renowned for their lightweight performance. Fully stress relieved, we carefully designed the barrel's taper to remove weight while maintaining performance. The result is the lightest barrel in the industry - and one we are fully confident to put our Faxon shield on.

Faxon's .308 barrels feature 1/10 twist rifling for full stabilization across all common .308 loadings. Our barrels are chambered to .308 Winchester SAAMI specification for maximum versatility. All our barrels are 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 goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.

The Gunner profile is a blend of two of the best performing profiles of all time, Gov't and Pencil. Faxon's Gunner profile combines the durability of the Gov't profile with the weight savings and maneuverability of the Pencil profile. The Gunner profile brings the balance of the rifle back towards the shooter's body, limiting fatigue, and allowing for shooting, training, or hunting all day long.

Faxon Firearms barrels are the pinnacle of value. Manufactured in-house in Cincinnati, Ohio, Faxon barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.

Designed for those looking to save weight while still allowing for the use of a suppressor long-term, the BIG Gunner is ideal for suppressed shooters. All for just about a single pound!

Behind the gas block will be a Government profile tapering to a shoulder and 1.1" journal .625 gas block. In front of the gas block, the barrel will continue straight to a 1/2x28 muzzle with full shoulder.

We've taken them a step further, adding in our patent-pending permanently attached SLIM muzzle devices. Shooters can choose from a 3 port muzzle device or three-prong flash hider, both allowing the full assembly and disassembly of gas blocks and barrel nuts. Shooters are forever free to change their weapon's configuration without having to go to a gunsmith.
