Machine Guns-- Private & Corporate Ownership
It is a common misconception that machine guns cannot be owned by law-abiding citizens. This comes from the creation of a variety of confusing laws that have made purchasing a full-auto gun more difficult than purchasing a "normal" gun. But, if you can comply with the law, you may qualify to own a machine gun.
