This is the firing version of the crossbow. This was molded by room temperature vulcanizing rubber which is used to make stunt versions. Therefore, this is the hero version. The stunt one is on Propstore's site. The reason I know this was molded is because the blue rubber is still in the cracks between the fibers covering the bow. The crossbow was made by modifying a pistol crossbow cutting off the trigger and grip. replacing the trigger with a metal lever and inserting the body inside a wooden frame.
