Re: vortex
Just got home from putting 55 rounds down range from 100 to 400 yards out of the GAP 308. Put the shims in for the zerostop feature, stops .5mrads (5 clicks) past my zero...works good. Clicks are well defined, glass is bright and clear. The eyebox at 24x is fairly tight but it helps keep me honest with my checkweld.
No regrets. May get another for my 6.5 Grendel AR.
Do some searching, there is alot out there on this scope.
