The Engler MP40 Paintball Submachine gun is a close reproduction of the German MP40 used during WW2.  (Of course this one only fires paintballs, not 9mm bullets).  The original MP40 has been made a classic by just about every world war two movie.  This submachine gun was issued mainly to squad leaders and paratroopers.    The Paintball MP40 uses a Tippmann X7 Phenom inside.  This gun can take 4-6 weeks to deliver as it is built for each order.
