    Hi Reaper69.....welcome to TFF. :)

    AO or A/O stands for Adjustable Objective. It means that the rifle-scope is equipped with a focusable objective lens to allow for parallax correction at various user-selected ranges. To be parallax free, the target must be located at the distance for which the scope is focused.
