*Though we stock barrels for builds, stripped barrels are usually drop shipped from the manufacturer in retail packaging. We cannot guarantee the accuracy of the “in stock” status. We can however accept back orders but please check Faxon’s website for availability.

Manufacturer Description:

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 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 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.

Faxon manufactures all our barrels in Cincinnati, Ohio under our ISO:9001 and AS:9100  quality certifications.

*Note – Faxon Firearms barrels are chambered to SAAMI specification .308 Winchester at a nominal headspace depth (passing “Go” and failing “No-Go”). This ensures maximum safety and accuracy.

7.62×51 NATO is not the same round as .308 Winchester, though it will fit within chamber. 7.62×51 technically requires deeper headspacing to meet the military specification and is known to function in Faxon .308 WIN barrels under most circumstances. However, due to the variation of components in the .308 AR world and variations between loadings, Faxon cannot guarantee or warrant function with 7.62×51, especially with bolts with tight (“match”) .308  WIN headspacing.
