I just recently found out where they all went, one word, Hollywood. Hollywood is the single largest owner of the Tippmann SMG's. They own them because they are so durable, and because of the way they feed, they make their own special "paintballs" which are really flash powder and use these guns to shoot them. There is one store in FT. Wayne Indiana that knows everything there is to know about these guns and this is what they told me.
