1971 40-x in .308. Beautiful stock, stainless barell , Olympic front rear sights. I was thinking about adding a Scope. I want to stay as close to period as possible, some suggestions have been Weaver K4, or of course the Rem 20X ($$$$) . I am a 100-200 yard Target shooter at a range for fun. this has been a fairly new hobby for me and really enjoy vintage. I have 52-b's, with litschert's some SP-1's w/orig Colt scopes so you can see where I'm with this. this stuff I will be passing down in the family. Any thoughts would be great
