And it starts with about $20,000 on average for a "cheap" automatic, assuming you want to tote around a rifle or a submachine gun. But if you want an automatic pistol...well...you better have a lot of money. To my knowledge only the Beretta 93R is on the registry, and there are single digits of them and even dealer sample (not civilian legal or transferable) are $250,000+. A civilian transferable 93R is probably going to be close to $1,000,000 if one shows up for sale.
