I have had a bunch of low cost Bushnells about 20 or so. NEVER had any kind of a problem with any of them. I have had as many Tasco scopes. Never a problem of any kind with any of them. These scopes have been used hard and have been on hard recoiling rifles. As someone else mentioned The Swift scopes at about 100 dollars are very good reliable scopes. I have a couple of Taso Prog Horn 4X scopes that have several years of service on them now. No Problem. They were 19.00 dollars when I got them. They are about 30 now. I have Luepolds as well as OLD Redfields. Have not used the new Redfields but on looking at them they are about the clearest scope I have seen.
