The Stormtrooper ROTJ E-11 is made from the same Sterling SMG model gun as the DH-17. U-tracks are heated and bent aluminum strips painted black and riveted to the barrel. The scope rail is custom made and the front scope plate is repurposed from the italian Ro72 pellet gun. The scope is made from different vintage scopes and the greeblies on the sides are metal 3d-prints, now identified parts from other modelguns (unidentified when I built mine). Now you may think I´m a gun fanatic, I´m not, I just love building things.
