So you need an AR15. Why?
The question is not about whether we need an AR15 or not. AR15's have no place in society. There is literally no reason a civilian population should have for using an AR15. None, zero.
But if you have no method or procedure to remove them from the bad civilians, then you need to let the good civilians keep theirs. I've said before that I would give up my guns if you could somehow get rid of all the illegal ones on the street in the hands of the bad guys. But you can't - and you continue to ignore this one deciding factor.
Since you are unable to get the bad guys to give up theirs, you will be unable to convince the good guys to give up theirs.
