Ok first off I know I'm going to catch alot of flack over possibly doing this this to my old winchester 69a 22lr. I have been wanting to mount a scope on it I know it's going to depriciate the value imencly but I've been thinking about have it drilled and tapped for a weaver base since the one I have isn't the variant with the dovetail grove for a scope. I wanted to know if anyone knew what number weaver base it took i'd heard that model 80 bases will fit. Any info would be great thanks.
