The AO will be handy on any scope. Most non AO scopes come with rhe parallex set at around 100yds. On lower power scopes we do not notice small differences in cross hair movement or focus but it is there. On higher power these things become more pronounced just like any movement when trying to hold steady. I have a 4x16 sweet 22 scope with AO even on 4x and shooting at 10yds the AO cleared that scope up a lot. It was stated he wanted the scope for every thing including target shooting. In my opinion get the AO and have no regrets and remember low power does not make parallex go away.
