The Rorynex RM-3/XXI is a popular Submachine Gun produced by Rorynex Industries which uses a slightly smaller bullet than in standard models in order to increase its range. This also allows the weapon to carry a much larger magazine, which it can empty quickly on full-auto firing. Bullets fired by the popular XXI are explosively-tipped which, combined with its other qualities, makes it illegal on hundreds of worlds across the Inner Sphere.
