My older scope has a problem with the adapter fitting over the eye piece. I had to sand it down and it still has a bit of an issue fitting properly. I understand that people are using it on newer models, but I take great care of my equipment and I still have the scope I’ve had for nearly 20 years. I’ll be sending it in for service after my trip to Tajik this year. It’ll be the first time I’ve ever sent it in. Jesse
Excellent fit and retention.
Fit great and worked like it is meant to work.
