This beauty was a result of the combined efforts of both myself and another talented sculptor named Gary Jensen. It's a faithful reproduction of the shoulder cannon from Alien vs Predator, or AVP, for short. It was originally sculpted in a material called ultracel. I added the micro-detailng and made the mold for casting editions of this monster. It's over 16" long and has a sliding pump section that was a challenge to make a mold from. But in the end, it has become a legend in the Predator forums and raised the bar for fan-made costume props.
