As it is now, Class III rifles are very difficult to come by and are very expensive. They can run $12,000 or more depending on what it is. There is tons of paperwork to fill out, a local sheriff needs to sign off on it as well as the Feds. It takes 6 to 8 months to actually receive the rifle after all checks go through. Another thing. Unless, you are a Class III dealer with a type 2 license I think it is, you cannot purchase any full auto made after 1986. So, I can buy any full auto made prior to 1986, but anything after, I cannot without the proper licenses which are very expensive. A Coworker spent $25,000 to $30,000 the other year for a vintage Vietnam era AR10. It took him a full year from the time he filled out the paperwork, paid the tax stamp and had all of the necessary checks done before he had that rifle in hand.
