Star Model Z84
The Star Z-84 was a Spanish selective-fire submachine gun originally manufactured by the now defunct Star Bonifacio Echeverria, S.A. The Z-84 is a sturdy, well-designed weapon that never saw high production due to politics. Originally manufactured for use by Combat Swimmers, the Z-84 could be used right out of the water without any need to drain the working parts or magazine, known as over-the-beach or OTB capability. History The Z-75 was Star's modern, 3rd generation, SMG chambered in 9mm Largo. 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 receiver was of stamped steel, with a square-section bolt riding on rails internally. It fired from an open bolt in the same method as the earlier weapons used, and had the same 20 cm (7.85 in) barrel length. It weighed 2.6 kg (5.75 lb) unloaded. The Z-75 was a commercial development project that led to the almost identical Z-84 and the Z-75 never went on mass production. 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
