OK, so i have an older rifle that i added some taller scope rings to. Well, when tightening the windage adjustment screws, one of them broke...the head broke off. The threads backed out of the mount itself with no problems. Im not sure if the screw was weak, or i just got over confident with it. Either way, Redfield is out of business and leupold doesnt make a screw thats similar. Does anyone have any ideas as to what i can do to get a replacement?
