Assuming you don't live in a state that forbids it. Yes, you can own a automatic weapon if you go through the 6 month to a year long federal, state and local background checks and purchase a $200 federal tax stamp. And then you can take approx. $25,000 and up and try to locate a registered lower receiver for a M16 produced before 1986. The video shows it is a M16 by the shape of the lower and magazine well area, with a modified upper.
