u could go with the baush and lomb scope and mounts the rear mount bolts in the peep sight holes u could modify it or go with a balvar 8 scope if u end up with a foggy one theres a guy here in the states that cleans and puts a new reticale in it and there like new. the matt receiver and deep blued barrels and parts is factory i think any modifying it you would throw 500$ out the window.has to be one of the earliest magnum supergrades out there. i wish my prewar wasn't tapped if not i have a stith mount coming on a pre 64 in a couple of weeks
