This time you are wrong. Under federal law, anything that can fire more than one round per trigger pull is a machine gun. If you have one without having the proper tax stamps, which they no longer issue for any weapon made after 1986, you cat, your wife and your children, even if they are still in the womb, are in grave danger.
Concur on law - but, I trhink the definition used in law was purposefully made to make non-machine guns subject to machinegun restrictions.
