they will be what;s called dealer samples, ONLY open to those with a class 3 lic, or to law enforcement, NOT the general public, due to the status of the guns as they are!

they will most likely end up in a collection of someone, or to a shooting range that rents full auto's
there a fun gun, had the chance to have one in shop for a while, sent a lot of rounds down range with it too LOL

they can pull some crazy prices too if they were transferable to everyone(where legal to won that is)
