Star Z-84
Star Bonifacio Echeverria · Submachine Gun · Discontinued · 1985
Also known as: Star Model Z84, Z-84
Overview
The Star Z-84 is a Spanish 9x19mm Parabellum submachine gun developed by Star Bonifacio Echeverria in the mid-1980s as a successor to the earlier Z-62 and Z-70B. It uses a simple blowback, open-bolt action with a telescoping bolt that wraps around the barrel, giving a compact overall length. Designed to be exceptionally rugged and sealed against the elements, it could be fired straight out of the water by combat swimmers without first draining the action or magazine, and fed from 25- or 30-round detachable box magazines through a magazine well integrated into the pistol grip.

Background
The Z-84 was engineered for Spanish combat swimmers, sealed so thoroughly that it could be brought up out of the surf and fired immediately, making it one of the few submachine guns purpose-built to tolerate full saltwater immersion.
