Well it took a few minutes but the muzzle threading is done, plus re-crowned with 90 degree recessed, put an AR muzzle break on it to protect the threads and new crown. Now to stamp it, spin it with 220 on a vertical belt and the barrel spinner, then sand blast the surface for the Cerakote Granite Black application. Decided to go full black, barrel, action, bottom metal. Little more work, but I do like one color better for myself on a bolt gun.
