Hi. I've been using a Bushnell 3200 Elite, 5-15x40 for a few months now and just love it. Extremely bright optics, although does get some lens flare when the sun hits it right. The AO compares pretty close to a measured distance. Mine reads 55yds at a measured 50yds. Adjustable down to 10yds, but haven't tested it at anything but 50. I have it mounted to a Diana/RWS 54 (scope killer) in .22, using a Beeman adjustable 1 pc mount. Have over 2000 shots with it, no problems yet. Adjustments are positive and repeatable. Everybody that has look through it comment on the optics, just real nice. I always keep it on 15x, so can't comment on zero shift with power setting adjustments.

Tony.
