Originally designed by director James Cameron around the Heckler & Koch MP5 9 x 19 mm sub-machine gun. This was found to have an insufficiently large muzzle-flash, and so Bapty armourer Simon Atherton substituted the .45 ACP Thompson SMG. A Remington 870 shotgun was cut down to serve as the `30 mm pump-action grenade launcher`, and was disguised using the heat shield and pump grip from a Franchi SPAS-12 shotgun, both being cut down to fit. Custom aluminium `shrouds` based on Cameron`s design were pressed by a car-body manufacturing company. A barrel vent, triangular barrel support, and sliding stock were created from folded steel, and a replacement pistol grip was carved from wood and painted black to replace the Thompson`s obviously old-fashioned contoured bare wooden grip.
