Kalo-BigBurger Inc.'s Model 55 uses the popular 7mm format. It features BBI's own, experimental 'Nano Mouscouri'-technology. Special nanobots (so-called 'Mouscouries') form a 'cushion' of air that absorbs the recoil from the gun. This makes the rifle small in size and easy to conceal. Release 57 uses 60,000 mouscouri-bots and features modified SkinCom (4th edition) technology.
