I have been using an EOtech on my AR, as well as a 3 x 9 scope. The first optic I got for my AR was the Nikon 3x9 , which IS better for coyote hunting out here in utah. If my day is dedicated to coyote hunting, it stays on the AR. I also do a LOT of jackrabbit shooting (hunting) out here as well, and there is nothing better (imo) than the EOtech for that. However...if I were to do it all over again, I would get the EOtech 1st. To answer you question, though, a good red dot or holograhic optic will definately do very well. I would not hesitate to shoot at a coyote under 300 yds with the EOtech (with shooting sticks),but, for my crappy eyesight, magnification is a big plus.However I HAVE nailed sitting jack rabbits at aprox 200 yds with the EOtech. I have mine mounted on a larue throw lever mount that absolutely holds zero after removal and reinstall. I might suggest the same for you. Good luck to ya.
