I had a Bausch & Lomb Elite 4000 6-24x40mm that I used for air rifle competitions. It was the only scope I could find at the time that went down to 10 yards on the AO (and was quite accurate at giving me the right distance so I could dial in my scope adjustments). It never shifted zero, and had bright, clearer glass than Nightforce. This was about seven or eight years ago, and I don't even know if they are making them in Japan any longer. Sadly, I sold that scope with the air rifle, but I did just agree to buy another exactly like my old scope,... but for the price I paid for it new back then! I think it's a fair sale, though, knowing just how good it was and how expensive it would be to replace it with something equal to it. If I could, I would have bought several of those things years ago. My advice would be to find someone that can verify if they're still making them as good as they used to. If so, buy a new one. If not, buy a preowned (mint) one. I know of something that is selling one in excellent condition, BTW,... the same guy I'm buying mine from.
