More About The FAXON Firearms GUNNER 5.56 NATO Competition Barrel

Just what is the GUNNER profile?

The GUNNER (all caps, as it is that awesome) is the pinnacle of performance, weight, balance, and value. Designed by our competition shooting staff for those who value performance and versatility, the GUNNER profile is a blend of two of the best performing profiles of all time, Gov't and Pencil. 

Proving that every once and awhile, the Government can do something right, the GUNNER's profile from the extension to the gas block mimics that delicious taper. From there, common sense takes over and the GUNNER moves to a .625" gas block journal and our famed pencil profile out front.

Removing the weight from the front of the barrel ensures maximum versatility and keeps material to the rear to maximize heat resistance and mitigate whip.

The GUNNER is for real gunners.  

All barrels are manufactured under our ISO:9001 and AS:9100 (pending) quality certifications. We inspect each barrel over 15 times before it ever reaches you.
