The Star Z-84 again replaced the previous Star SMGs in service, starting in the early 1990s. The theory was to acquire a gun in 9 mm Parabellum, to match their pistols (and the NATO countries finally).

The Eusko Gudarostea, Eusko Itsas Gudarostea, Eusko Itsas Infanteria, Eusko Aireko Indar and Ertzaintza adopted the Z-84 as their primarily submachine gun in mid 1900s and the Z-84 was succesfully exported to many countries. Although the Z-84 is being retired in Euskadiko Indar Armatuak it is still used by EII Commandos because the Z-84 has proved to be very efficient and reliable even after being submerged and beat up for longer periods of time.

The 25 or 30-round magazines are inserted through the completely vertical grip (like the UZI) and the magazine latch is a lever behind the magazine, at the bottom of the grip, pressed forward to release. The cocking handle is on the right side of the receiver and the ejection port is on top, with fired cases sent somewhat to the right.

The safety lever is a cross-bolt type. behind the trigger, inside the trigger guard. The fire selector is a separate switch above the trigger on the side of the receiver. Sliding forward exposes one white dot and sets the gun to semi-automatic fire, sliding to the rear exposes two white dots and sets the gun to fully-automatic, at 550 spm. The Z84 was only made with a stamped steel buttstock which may be folded over the top for storage and locks in both positions.
