Assault Rifle/Bullpup - 4.92x34mm caseless - Germany - 600 RPM - An amazingly high-tech weapon that was to be the German Army's new standard rifle.  With the unification of East and West Germany, the high cost of reequiping both armies prevented its adoption.  A few made their way into German Special Forces units. The 4.92mm round has no metal casing and completely combusts upon firing...no brass to police! D.E. Watters
