The Big Gunner Is the Big Bore Barrel That Has All the Features You Want

If you haven't built a modern sporting rifle with a Faxon barrel you have no idea what you have been missing. Faxon didn't set the industry standard by putting out sub-standard barrels like some of the other guys. No, they did it by placing an emphasis on research, design, and production. Faxon Firearms leads by example and if you haven't tried one of their barrels yet, what are you waiting for?

If competitive shooting or a duty situation is calling you to build your next rifle then you need to take a hard look at this Big Gunner barrel from Faxon Firearms. The Big Gunner .308 is the big brother to the smaller frame barrel of the same name. It features a medium taper behind the gas block and the gas seat is .750" which is compatible with most common gas blocks. The barrel is constructed from 4150 QPQ and features a inner and outer salt bath nitride finish. When seconds are precious, count on the Big Gunner.
