Faxon Duty Series 20", Big Gunner, .308 WIN, Rifle-Length, 4150 QPQ Nitride AR-10 Barrel
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.

Awesome as usual
Very accurate, perfect fit, and finish. About 200 rounds in, and it's a tack driver!

20” Big Gunner .308win
I haven’t installed it yet, but Faxon got it to me quickly. The finish is immaculate. I’ve purchased from Faxon before, and have been impressed by their quality. I can’t wait to try it out.

Balanced
This makes a great SPR/DMR barrel as it drops a significant amount of weight off the front of the gun to make it much more maneuverable. I was able to shoot a 1.125 inch group at 100 yards with the first 4 shots being well under an inch. I really think the barrel profile is the perfect balance between sturdy enough for a suppresor or moderately extended strings of fire but light enough to easily fire unsupported. Mine ejects at 2:00 to 3:00 with a 5.6 oz buffer; so, it's moderately overgassed. Otherwise, it's perfect.

308 barrel
Awesome barrel, fit perfectly and was packaged very well to protect it from shipping damages. Please get a chart for gas tube lengths needed per barrel so I can order the correct one the first time.

20” Big Gunner barrel AR 308
Great barrel for the price. Built as a hunting rifle and shoots <1 MOA with hand loads.

Good weight and finish
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.
