Well, you omitted that making one of these has been illegal since 1986, for individuals. should a person buy this kit and complete it, they have illegally mfg'd a "post '86 machinegun" which could earn them 10yrs in fed prison, and up to a $250,000.00 fine.
Phoenix01, follow the advice of the other poster's, look on subguns & the sturmgewehr board for a legally registered item.
knowlege is power.
