Sniffer - I think the best thing you can do for yourself is to do a lot of reading on optics and read some scope reviews for models in which you might be interested. Forum posts are not a good medium to share this type of information and it's just a big area of study.
From what you have said I suggest a Sightron 10-50X with a target reticle. It's nice to have the extra magnification when you can use it and if you are not moving, a heavier scope doesn't disadvantage you. It would be ridiculous putting it on a 7.62x39 shorty AR which is where we started.
p.s. Any decent scope with more than 10X will have parallax adjustment.
