I've decided on a set of Millett angleloc adjustable rings for my CZ527. Now I just need to figure out my actual ring height. I am mounting a Luepold ultralight 2-7 28mm Obj. I think I can get away with a low ring, but in my searches I have seen some problems with the low rings and bolt handle clearance mentioned. I want to mount as low as possible but don't want to mess with bolt handle clearance. Anyone mounted one of these sets of rings on a 527?
