I have been hunting coyotes with AR's for a long time, most of mine are a bit on the heavy side as well. I have built several over the years to be coyote hunting specific and they always seem to end up a pound or two heavier than I planned. I always try something different when doing a build to see if it makes it better for coyote hunting. My current AR sports a 1-12" WOA 20" barrel, JP trigger, billet side charge upper with a Leupold 2.5X8 pushing 10 pounds. I never go hunting with just one rifle, I will pack my 6 pound .222 in the truck in case I have a looooooong walk to a stand or in wide open country I will take my 16 pound 22-250AI and see if I can hit a 800 yard coyote with an 80gr VLD
