I don't use AR's, but others are welcome to use whatever they want.
Illegal activity isn't tollerated around me, but others are welcome to use whatever firearm and tactics are legal, as far as I'm concerned.
As a note-
Way back in the mid-1980's a buddy and I invited a friend to go predator calling with us. We both used bolt action rifles, and the friend wanted to use an AR-15.
He started giving us a hard time about our rifles, saying we weren't going to get anything, because he was going to "rat-tat-tat on 'em", and we would only get one shot each before he killed whatever came in.
Long story short, I killed two coyotes in two shots on the first stand. We got nothing in on the 2nd stand, but called another in on the 3rd stand. Tony saw it first, and opened up with his AR.
We were on a mesquite flat, so I stood up to see what was going on. I saw the coyote running at about 250 yards, and heard Tony's rifle click, so his 15 or 20 round mag was empty.
Yep, I dumped the coyote with one shot from my .243. I hit it through the hind quarters, so it was still alive for Tony to finish off.
I know some fellas who hunt with AR's and make every shot count. I've seen them take doubles and triples on a stand, and it's a wonder to see. Personally, I still like bolt action rifles for hunting, and I'll continue to use them because I kill just as many coyotes as anyone else, and sometimes more.
