15 inch 209×50 magnum muzzle loader pistol barrel, the muzzle is threaded 3/4×24 for a brake is need be or just a thread protector. It was a rifle barrel cut to a standard 15 inch pistol length so it uses longer rifle length hand guards. It was drilled and tapped for the original iron sights when the barrel was cut down so you cat still shoot it unscoped. This is for a TC encore.
