Faxon 20" Big Gunner Profile AR10 Barrel, 308 Win, Nitrided
- Usually ships within 2 business days.
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.

This is my first Faxon barrel and I'm definitely going to get more. The finish is excellent, the fit was amazing. Headspacing was spot-on. I was a bit confused by the two colored dots at the top of the extension, but not a huge deal. Gas block OD was *perfect*, as Ace Ventura would say, "Like a glove!" Crown was spiffy as hell and the weight overall is very good. Definitely worth it.
