The Hughes Amendment was not properly voted into the Constitution the day of April 10, 1986. This amendment is not legitimate due to a clerical error. Here are two links for evidence:

The opening of a Machine Gun Registry would allow all law abiding citizens of the United States to have access to machine guns and machine gun parts. These citizens would still pay the $200 tax stamp currently required to own most NFA items. The Hughes Amendment is a blatant violation of the 2nd amendment. It is considered unconstitutional by the 2nd Amendment and therefore should be rendered null and void.
