please help me chose a scope
i just recently purchase a RRA 16" predator pursuit in .223 for hunting varmints and plinking and i need some glass on it. shots will be relatively close range on this gun. i also have a rem700 sps-v in .308 that i use for hunting and would like to start doing some long range shooting with. it currently has a little nikon 3-9x40 scope on it to get me by. my primary goal is to get glass on the AR. i do a lot of spotlighting for predators, so i need a scope that will do well in low light and at night.
i have kind of narrowed it down to zeiss conquest 3-9x50 with zplex or SWFA's SS 3-9x42 ffp mil/mil with the new mil quad reticle. the zeiss is a little cheaper, but doesn't have the tactical long range features that the SS does. i am assuming the zeiss has better glass though. i had planned on getting the SS for my .308 at some point anyways. getting it now in a QD mount would kill two birds with one stone. however, the .308 has a 20 moa base while the AR is a flat top. this means i would have to resight both guns everytime the scope moved back and forth right?
what do yall think i should do? part of me thinks i should just get the conquest now since it is geared more towards the type of shooting ill be doing with the AR, then worry about better glass for the .308 later on when funds allow.
sorry this is long, thanks for reading
