I really hope they make an issue of this. I'll bet my last case of ammo the anti's couldn't tell the difference between an AR15 in an assault rifle configuration or a sporting rifle configuration, even if the two were laid side-by-side.
Don't be silly.
They'll answer it in the twinkling of an eye.
It'll go something like this:
Those are BOTH assault weapons! And if by some LOOPHOLE, the evil manufacturer has managed to get ONE of them to market, we need to FIX the loophole, NOW!"
