I recently got a CZ 527 and was going to mount a scope yesterday a Leupold 4.5-14 . I had purchased a set of Warne med height rings and they were a fraction of an inch to low. Where the bolt handle attaches to the bolt touches the rear scope bell, what a pain. They were a special order so I have to send them back and wait to get the high ones. O well, be nice when it gets done. Cheers Roscoe
Edit, not sending back now, sent bolt handle to James Calhoon in Mt. USA to do do a lowering mod. Cheers
