What you say is correct but perhaps incomplete. Research the cost of a fully automatic firearm (exclude post sample units). Because the supply was restricted to only those already in the hands of civilians by the Firearms Owners Protection Act of 1986 (boy, was that a misnomer), the price of fully automatic firearms skyrocketed. On the average, you can't touch a transferable Class 3 firearm for less than $15,000. Consequently, in order to own a fully automatic firearm, a citizen must be solid and financially "comfortable".
