zeke, I don' t have a mount or ring problem, I have put on enough scopes to know what I' m doing, the mount was never bothered between my old scope and new scope and then old scope again, the rings where very tight, it would group great as long as you did not try to adjust it, once you did it might shoot several inches off from just a couple clicks, then you could shoot it 3 or 4 times and you could cover them shots with a quarter, the scope grouped good, the rings and base was tight, guaranteed.

I truly think that this is a very rare deal with a leupold, but I do and did have scope problems and not rings or base problems.
