She does realize fully-automatic weapons have been tightly regulated since the 1930s?

The National Firearms Act of 1934, the Gun Control Act of 1968 and the Hughes Amendment in 1986 have all placed limits on how automatic guns can be bought and sold, but did not make it illegal to possess them entirely.

Purchasing one requires submitting fingerprints and photographs to the Bureau of Alcohol, Tobacco, Firearms and Explosives, going through an FBI criminal background check, and paying a $200 tax, among other requirements. Only automatic weapons manufactured and registered with the federal government before 1986 can be bought, owned and sold.
