Assault Shotgun/Bullpup - 12 Gauge (Tungsten Alloy Buckshot) - USA - 240 RPM - A futuristic design, the Pancor Jackhammer was surprisingly not entered in the US Army's CAWS trials.  The gas-operated weapon is fed from a 10rd pre-loaded cylindrical magazine and uses a method of cylinder rotation very similar to the curious Webley-Fosbery semi-automatic revolver.  The Jackhammer has not entered series production, and the inventor is trying to sell the patents, prototypes, and production rights for $330,000 (US). D.E. Watters
