I have an opportunity to purchase this scope from the original owner of my Remington 40XBR who bought both as a package in 1973. Both the rifle and the scope are in mint condition. Was wondering if there are any BR shooters out there who might comment on how these externally adjustable scopes compare to modern optics as far as clarity, brightness, and resolution etc. Aside from the sentimental merit of reuniting the two, should I just stick with my Leupold target scope and forget about it? It comes complete with tube, mounts, bases and factory literature. It's a blast from the past so to speak but can the scope still cut it? He's not exactly asking peanuts for it.
