It's not legal to possess or transfer private ownership of any FA weapon that isn't included in the BATFE registry which was closed in '86. FA weapons manufactured or imported after '86 can only be owned by military, law enforcement or anyone registered with the BATFE as a Class 3 firearms manufacturer or dealer.
The guns you see on YouTube are either pre-'86 weapons or they're owned by a manufacturer/dealer. They're not privately owned if they were made after 1986.
Buying a pre-'86 FA weapon in the US is not particularly difficult in most states. It just cost a lot of money and a lot of paperwork.
