Faxon Firearms 20" GUNNER 5.56 Nitride AR-15 Barrel

High quality AR-15 barrels by Faxon Firearms.  All Faxon 5.56 barrels are MPI and Proof tested.  Faxon only uses the highest quality materials and manufacturing processes.  These are simply better than any other barrel in their price range.  Made in the USA.

The GUNNER is the pinnacle of performance, weight, balance, and value. Designed by Faxon's 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.
