Each Faxon barrel goes through a battery of tests at each operation until finished and final inspected.  All barrels are individually checked for headspace by precision custom hardened gauges.

The Gunner profile is a blend of two popular profiles, Government from the extension to the gas block, to a .625″ gas block journal, then a Pencil profile out front.  This barrel has a pistol-length gas system for optimal reliability with both subsonic and supersonic ammunition.

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.
