Faxon 6MM ARC 12.5 Gunner Match Series Barrel

Faxon 6mm ARC 12.5 Gunner, designed by Faxon's competition shooting staff.

Manufactured 100% in-house from gun-barrel-quality bar-stock, the Faxon 6mm ARC 12.5 Match Series starts with 416-R in the 5R rifling. The 5R rifling minimizes jacket deformation, increases velocity and ease of cleaning. Read more about 5R rifling here. We chamber our Match Series in 6mm ARC, a hybrid chamber the 5R rifling takes full advantage of with lands opposite grooves and reduced sharp angles that reduce jacket deformation increasing velocity, and easy cleaning.  After rigorous testing, the barrels are Nitride treated inside and out, locking in the bore, improving barrel life, and keeping the elements at bay.  Better accuracy through less bullet jump, but fully and individually MPI tested for your safety.

The extension is coated in Nickel Teflon which maintains incredible dry lubricity, corrosion resistance, and with the coating, tightens up fit between the extension and receiver - again improving upon accuracy. Combined, the Match Series of barrels are ready for when duty calls or the buzzer beeps with unrivaled performance value.

Just what is the Gunner profile?

The Gunner profile is a blend of two of the best performing profiles of all time, Government, and Pencil.

Proving every once in a while, the Government can do something right, the Gunner profile from the extension to gas block mimics that well-known taper. Innovation then takes over and the Gunner moves to a .750" gas block journal and our famed pencil profile out front.

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