OP - this works best when you remove the bolt for the Cooey - see other recent threads about how to do that. Lets you drill and tap straight through and also allows you to visually bore sight. You will want to get a Weaver #2 side mount base and either the short or long side mount ring assembly that fits the scope that you plan to use. I have mounted several low power 1" tube scopes with the short ring assembly - might need minor filing depending if the scope has a "lump" at the turrets. Mount your scope in the rings (no need to tighten screws more than "snug" for this test fitting), then attach the ring assembly to the side mount base. Either in a firearm vice or a cardboard box with a couple notches cut to hold the rifle vertical, fit the whole assembly to the side of the receiver. move it around as needed until you get scope and barrel aligned. Mark, drill and tap one hole. Mount base with that one screw, then bore sight assembly and adjust as needed. This is a situation where starting with the scope reticle centered will be a great help (place small mirror in front of scope - about 1/8" away - look through scope and adjust windage and elevation until reticle exactly matches its reflection - places the reticle in deep center of scope.
