That's wrong. IIRC, the NFA only requires that machine guns and silencers be registered and taxed. See this Forgotten Weapons episode: https://www.youtube.com/watch?v=po715YGEzTY. It's for a fully automatic M-16 with a device that makes it sound like an AK-47 that's regulated as a silencer. It was up for auction, but the winner would have to pay double the tax because it's a "two stamp" gun.
