Thread: Scope mounting for an old Harrington & Richardson "Plainsman"

Recently acquired can old H&R .22 "Plainsman" that came with the original metal sights and I wanted to put a scope on the rifle. It comes with what looks like dovetail rails, but with a curved not flat top. The "dovetail" also looks quite shallow and the pair of 3/8 dovetail rings that I have do not appear to seat very tightly in the grooves. Has anyone had experience with older rifles like this and can you provide some advice on the type of mount that I should be looking for? Will post some photos later to show.
