I have a Meopta 6-24x56 RD and it’s very good in low light and under lamping conditions,daylight is great and tracks well ,but dont think a rear adon will fit, but they do a 6-18x50 with side focus/parralex that should fit and is a great all rounder. Just depends on what you want to spend and everyone’s eyesight is different,try and look through a few friends scopes and see what you like and can afford.
