Whats the best optic for my M82A1?

[hatidua]

European glass is tops, all the others fight for second place. Doesn't matter if discussing photographic lenses (Schneider/Rodenstock/Leica), binoculars (Leica/Kahles/Swarovski/Zeiss) rifle scopes (Zeiss/S&B/Etc) -if it didn't come from a country with German as their primary language, it might not be the best there is in terms of optics, just the nature of the beast. There might be optics with more features, magnification, sex appeal, etc. but European glass is optically as good as it gets.
