I can't give you an answer, only some questions.
Which AR? "AR" covers rifles from an AR-22 in 22LR to an AR-50 in 50 BMG. How much recoil wil the scope need to withstand?
An "AR" can weight from 3 pounds like a carbon 15 pistol to 25+ pounds. What does the scope weigh? How far do you have to carry them? How much can or do you want to carry?
An AR" can have a useful range from 200 yards to a mile+ . How much vertical adjustment does it need? Can you use the scope to help estimate wind speed and wind deflection?
The characteristics of the target, such as it's distance, its motion, it's size, its visibility, how long it's likely to be visible, d and the time of day it might be visible have more to do with scope selection than what rifle is used.
I'm not surprised you haven't received an answer. I have AR-15s with many sights and scopes from metallic peep sites to an AN/PVS-12 night vision scope. There are $30 Chinese scopes which may be fine for plinking rabbits in garden or situations where nothing less than a $30,000 thermal scope would do the job. There is no multipurpose scope which will do a good job on all targets at all distances in all lighting conditions especially if quick target acquisition and range finding are required.
If you state the cartridge you're using and more importantly the target and general situation you'll l get a lot better answer. What do you consider "tactical"? To me that can mean QCB at under 25 yards, sniping at 1000+ yards, plus everything in between No one scope does all of that well. What sights might work best for prairie dogs mostly depends on the terrain you're trying to control.
