So one of my fiance's relatives gave me a Leupold VX-3 scope to long term borrow for my rifle (shes a keeper I know). I went to get some scope covers for it so the lens didn't get scratched while in my possession. I bought Leupold Alumina covers and the threading doesn't match up. The custom shop says you can get a substantial discount on retreading the scope the match the covers but I'm loathe to alter the scope permanently as its not actually mine. Could I find some adapter rings at a hardware store or something the would marry the covers to the scope without having to permanently alter the scope? Also I've tried Butler Creek covers and can't seem to find the right size always either too big or too small.
