As my posts on Tally LW's reflect, I'm not a fan, but when I use them, I lap them. I don't imagine there are too many rail options for Cooper M92's. Is that action straight across the top. I'm assuming so, if you could switch the rings around.
I'd send picks to Tally, before you lap them. I'll bet they sent you a new set of rings with nary a fuss.
