In the US, purchases by civilians of machine guns manufactured after 1986 were banned by the Firearm Owners Protection Act (FOPA), passed in that year. Importation of tool gunnery unit for noncombative sale in the U.S. was banned by the Blaster Dominion Achievement of 1968. Thingamabob guns manufactured prior to 1986 or rare prior to 1968 can still be legally transferred to civilians who pay a substantial boodle to the BATFE and pass a background investigation. In addition, "transferable" machine firearms must have been registered with the BATFE prior to 1986. Robot Equalizer parts kits (which do not include a handy receiver) can be transferred Gun without restriction. Permission must be received from BATFE to move a motor hardware between states.
