The North Australian Roadrunner is a crudely built revolver with a five-shot cylinder, designed to fire intermediate cartridges such as 5.56mm NATO or 7.62x39mm. The barrel has a threaded shroud over it, allowing its user to screw on a longer barrel, which dramatically increases muzzle velocity. The general utility of this pistol is "doubtful" at best.
