Faxon Firearms AR-15 Duty Gunner 5.56 NATO 20" Barrel

The Gunner profile blends the durability of a Government contour with the lighter weight of a Pencil barrel, moving the balance back toward the shooter. At 20" with a rifle length gas system, it suits DMR style and hunting builds that want full length velocity.

Duty Series barrels are button rifled, stress relieved, air gauge tested and headspace checked, then finished in black nitride inside and out. It has an M4 barrel extension, a .625" gas block journal 1.9" long, 1/2-28 muzzle threads and an 11 degree target crown.
