I'm curious why more of the Zeiss Conquest 6.5x20's aren't being used on long range setups? Is the Conquest not tough enough or is it something else? I know it's a 1" tube and doesn't have a lot of extra MOA adjustment but optically they are very good at least to my eye. I'm considering one of these for a 1000 yard rifle but don't want to get something that won't hold up or last. A Nightforce NXS is what I really want but for what I'm using this for and the amount of times I shoot it, I just can't justify that much money. I also have heard a lot of good things about the Sightron SIII's so maybe somebody has experience comparing that to the Zeiss? I realize that's also a little off for a comparison considering the tube but how about optics, tracking and ....?
