Star Z84 SMG

The Star Z-84 was a Spanish selective-fire submachine gun originally manufactured by the now defunct Star Bonifacio Echeverria, S.A.
It superficially resembled the UZI, and incorporated the modern features first seen on the Czechoslovakian Sa vz. 23, such as an overhanging bolt, to reduce overall length.
The Z-84 is a 9mm Parabellum, blowback operated, selective-fire, capable of fully automatic firing, open bolt weapon which heavily derives from Z-75. Having very few moving parts makes it a very simple weapon to operate and maintain. Made mostly of stamped and cast parts, little machining is needed to produce the weapon.
