Umarex Marlin lever action muzzle

replacement muzzle for the Umarex Marlin lever action bb gun, didn't like the fat style that the gun came with, also added a rounded sight post to fit the ghost ring rear sight. Stabilizes inner barrel for better accuracy, DO NO FORCE IT ON, for best results heat both the part and outer barrel with a heat gun before and as installing, hole included for replacing the set screw but not entirely necessary.
