stuck the gun on some shooting bags. Levelled it on the breach. Moved the level onto the front sight dove tail which is basically a sleeve held on with a grub screw. Its slightly canted. This is an easy fix a couple of slither of shim on one side will straighten it up. The rear sight however is different. The rail is level but when i clamp the sight onto the rail the sight cants over. When i look at the dove tail it seems to be concaved in the corner where the dove tail is supposed to meet.
Not sure i could shim it as the dove tail may not fit afterwards.
Maybe the sights are supposed to be slightly canted?
