So I picked up an aimpoint red dot scope for my AR. Use will be for coyotes. I've sighted in etc. I'm not 100% sure this is my thing. I might prefer a simple scope with magnification. Can anyone give me some of their experience using one of these for coyote hunting? Good and bad. I worry my eyesight isn't as good as it used to be so without magnification it may be tougher when targets are out 100+ yds?? thanks
