Manufactured 100% in-house from gun-barrel-quality bar-stock, the Faxon 6.5 Grendel 18″ Gunner 5R Match Series Barrel 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 6.5 Grendel, a chamber the 5R rifling takes full advantage of. Better accuracy through less bullet jump, but fully and individually MPI tested for your safety. After rigorous testing, the barrels are Nitride treated inside and out, locking in the bore and improving barrel life.

The Nickel Teflon coated extension maintains incredible dry lubricity, and corrosion resistance. Combined, the Match Series of barrels are ready for when duty calls or the buzzer beeps with unrivaled performance value.
