An A R 's accuracy depends on a lot of things the same as a bolt-action rifles does . They like all other things have evolved over the years and improvements have been made , a lot depends on who puts them together on the civilian side of it as to how well they shoot groups . As for my coyote hunting I still like a good bolt action rifle mostly because that is what I grew up with . A223 running 55 grain Sierra boat tail hollow points for normal calling and a 6.5x284 running 120 grain Nosler ballistic tips for things at a little more distance . You guys might try an M14 there were a few of them still in use in the brown water taxi service till around 4/29/1975 . I don't really care what branch you were in you are still in the original 1 percent club good and bad in all of them, people are people some of them are upstanding and some not so much .
