thanks bronko. i had a t/c do the same thing about 25 years ago. but tc covered it under warranty. as for the traditions i'm going to remove the sights anyways. with my new set up on the scope it hits the rear sight & on low power i can see the front sight. but i still want to get a newer tc impact with the speed breech. but right now without working i'll keep what i got .and found out yesterday i may have another set back coming down the road . will let you know what's happening soon.
