This is good to know, thanks. I've had lots of experience with many scopes and many calibers, but this is a first for me with an AR and short range rifle shooting (asssuming the coyotes I call come in close). I've called coyotes to within ten feet and have missed shots at very close range, like 25 yds, because I couldn't get the scope dialed back soon enough. It sometimes happens very quickly. At this point, this is experimental and I can always go back to longer traditional scopes. The rifle will be done this week!! I'll let you know.Keep in mind that a scope with an objective diameter of 24 mm and a maximum magnification of 8X is going to have a very narrow 3 mm exit pupil at maximum zoom. There is no getting around this, it is physics. That means that at high magnification, your eye box will be very narrow and your shooting eye will need to be very precisely positioned to achieve a full field of view without vignetting. In dimmer light, the diameter of your pupil is going to be significantly greater than the exit pupil of the scope at 8X.
