It seems the spectre of the Assault Weapons Ban will never go away for some. As recently as April, I heard someone claiming that pre-ban mags were illegal. They were under the impression that you could own standard-capacity mags, but that they had to have been bought after 2004.
I don't know where people get this stuff. I really don't. There's no restriction on magazine capacity in Georgia, or in most southern states.
ETA: even if they say something like "restricted to law enforcement/military" or somesuch. None of that has any force of law.
Sometimes it’s nice not to destroy the world for a change.
