I have a repro scope on one of mine and have a different problem. I simply can't focus on the target with my glasses on. Take my glasses off and it's just fine. Only scope I own that I have that issue with. Not sure if it is because of my aging eyes and needing bifocals now or what. I did get new glasses recently but haven't tried them out on it. Now my scope is a repro repro, not one of the exceptionally good ones. It's a Fairfield.
