I'm gonna have to take pics of mine tonite with the bsa scope on....I think the one I have designed the other way where I can't mount mine to the back. I cut the attachment in half to make mine work.The rail is a bit wide and the slots are spaced wrong for some scopes, like the 30mm BSA. However, it will fit. I'm using a Bushnell Trophy with no problems. I think you are better with a scope that allows the brackets to move, rather than fixed mounts. But either will work. Or try some different rings.

7" barrel with Bushnel
I'm sorry, my mistake. (Edit: My Bad, No Mistake; see new pic below). The Simmons will not fit without modification. (Edit: It will fit without mod). On the Simmons, both mounting pins must fit inside a corresponding slot. The forward pin has a linear adjustment range from about 1.5" to 2.0". On the holo sight I have, only the forward pin fits inside a slot, the rear pin sits above the rail. The 22A has a Weaver rail, the Simmons will fit a Picatinny rail. Weaver rails are not all the same, Picatinny's are the same. This might help.Ok thanks for the reply. It was late at night when I tried. I'll give it another try today. I'm sure I was doing something wrong. Appreciate the input. Steve
