ARES FMG

The FMG never entered full production. The weapon was unique, in that it is designed to be folded into a box shape, which can be unfolded and made ready to fire in a matter of seconds. When folded, the size is about the same as a cigarette carton, and the appearance is deliberately similar to an old-fashioned metal commercial radio. The ARES FMG can be folded with its 20-round UZI magazine loaded. A 32-round magazine was also available, but its use prevented folding the weapon. The original prototype was designed to use a World War II German MP40 magazine. The second prototype used UZI magazines and had a three shot burst mechanism as well. The weapon inspired a Russian, and a Ukrainian copy which are almost identical except for caliber, magazine and folding sights that were added. While descriptions of a fictional "ARES II FMG" exist on the web, the actual ARES FMG was only chambered in 9×19mm Parabellum.
