Do you really want to hassle over a silly AR that was his originally. I would tell him to send you a hundred bucks to cover shipping and handling and a FFL that he wants it sent to. Get your FFl on your end to send it to his FFL and make him yellow sheet it again. Then go buy yourself a new AR. If it makes you feel better take it out and do about 20 mag dumps as fast as you can pull the trigger u till the barrel droops and the throat is cooked but I would not get a lawyer to try and keep something as trivial as a rifle.
I'm sure we're headed to court one way or another, that's just his M.O. If he doesn't get exactly what he wants he threatens and takes us to court. A couple years ago we had to let our attorney go after our last time in family court with him. He decided that he'd only correspond with us through our attorneys. So we had a monthly bill of about $200-300 for attorney fees for email correspondence, and our attorney told us that if we "fired" him then the Ex was the only one paying attorney fees.
As far as I'm concerned if he gets a stripped lower receiver then we've sent the rifle back. However, he doesn't care about the rifle he just wants the ATF to secure it. He's just making trouble for us.
