I just need a pair or rings, but the have to be high enough to clear the rear sight when it is folded down. The rail on my Sport is long enough.
+1The Burris PEPR mount (or one like it, meaning a cantilever mount) is the one to get. It should allow the ocular end of the scope to clear the rear sight. I don't know what kind of rear sight you have, but the PEPR does in fact allow my Nikon M-223 to clear a Troy rear sight. The PEPR will also allow you to use scopes with up to a 50mm objective.
