Rear sight is way off and dove tail slide has been punched twice by factory.
Used punch and hammer trying to slide sight over, but won't budge.
Do they make a rear sight adjustment tool for the CZ52?
Which ever way it is sitting, either to the R or to the L, try pushing it on out the way it is already started and insert from other side when you replace it. Sometimes, parts are designed to only go one way...
