My AR`s are set up for coyote hunting. I have 3 x 9 Leupold scopes on 2 uppers, 1 in .223 and 1 in .204. They are my day guns, but I have never shot at a coyote with the scope set on anything other than 3X. For my nite rifle I have a lazer mounted on a .223 upper. I use gen 3 nite vision goggles anduse a red lazer that covers 4 in. at 100 yrds. It`s larger than I want and they do make smaller but I haven`t got 1 yet. I personally do not like the red dot type sights, but have a friend that used them for a while and I watched him hit a corn husk at 258 yrds. lazered.
