Generally, but there is a potential legal path. However, you have to jump through a lot of fiery hoops. And a legal, registered auto-sear would cost like $30k. I'm not sure if Sergio is in America. Overseas in less restrictive countries the price would be substantially less. The fact that he's got a full-auto sear package as well as a suppressor leads me to believe he's probably not I'm the United States. And if he is, this gun probably wouldn't be legal.
