Does any one know anything about belt fed guns. I have looked at one site called how stuff works but that gives me sort of an idea but i need something a lil more. does anyone have blueprints or plans for a belt fed gun. If you do that would make a great instructable. I know some of the basics of the belt fed guns, but not much more than that. I am wanting to make a 9mm belt fed LMG. Basicly from one of P.A. Lutys designs, only change them up a lil bit to use the belt feed.
