Unfortunately, the legalities of full auto ownership are tricky. This particular gun is a "Post-86 Sample" and is not available to everyday folks. It can be manufactured by someone like Gunfixr, a FFL/Manufacturer who has paid the "special occupation tax" (SOT), but can only be transferred to other manufacturers/dealers who have paid the SOT (provided they possess a letter requesting a demonstration from a law enforcement agency for that specific firearm) or governmental agencies. There are a number of other "transferrable" machine guns that can be possessed by regular joes after ATF approval.
