The point about locktite is true as many scope screws are fastened with it. I forgot to mention if you do not have a Weaver Scope Mounting Kit I would very strongly suggest buying on. It has ring alignment tools, bubble levels, inch pound torque wrench and the various sized allen wrenches you might need. At the same time I would order a "gun screw set" and you'll have the needed replacement BUT since you have a set you'll NEVER break another one!
