The standard submachinegun of the Spanish army, this weapon fires a 9mm round at a cyclic rate of 600 rounds per minute. Its small size and light weight make it a favorite of security forces the world over.
Star S.A. developed the weapon after a successful run of submachine guns based on the German MP-40 design. Realizing they couldn't rebuild the same weapon over and over, they built the Z-84 completely from scratch using modern designs and engineering. At the time of the Z-84's design, Star was building and importing large numbers of cheap handguns into the US. The 1994 Assault Weapons Ban (now repealed), banned the importation of many of their designs. This proved disastrous for Star and by 1996 had driven them into bankruptcy. Less than 1000 Z-84 were manufactured before the company went bankrupt but many were sold on a testing basis to various countries in South and Central America. The Z84 is still in use with the Iranian Takavaran commandos as it is found to be reliable in amphibious warfare.
