I like Simmons scopes and am very interested in checking out the Aetec. However, I have a SIGSAUER 202, and have two extension rings, but not sure the scope mounting area is long enough to give good eye relief. Last year I missed because I eveidently did not have a good sight picture and couldnt get the reticle close enough. I will check them out, but I may have to go to something besides Simmons because of the overall and mounting length.[&:]
