Too bad you had a lemon, its the the 3rd CP iv had, ner had an issue with em and two of em were used on a break barrel air rifle and held up to thousands of shots and croashaira never broke. I'm using the new one on a 22 mag but the scope has a couple hundred shots with the air rifle under its belt..no probs..like I said, got tired of the blurs with the other and decided to swap em out. It just shocked me how much clearer the glass was. I'm not trying to sell you on it, use what ya like. Just sharing my comparison.
