Repeatabilty on the the knob adjustments is very precise. The mil dots are nice for alternate aiming points for different ranges. The AO yardage markings are very close to correct.
Have this scope mounted on a Diana 54 with an accushot 1 piece mount with the recoil stop pin in the Diana scope rail (no locktite used). Seems to be a very good rig, nothing has moved in the last 1400 shots.
