The Hydrus carbine is a 9mm folding-stocked semi-automatic weapon of Red River origin that was first manufactured during the Hesperidesian Revoultions. The weapon was intended as a self-defense for white farmers.

After some delays, primarily due to wartime interruptions, the Steelwater Arms Company started the manufacture of the carbines in 1977, and after a month the production was then taken over by the Acconia Armoury which continues to produce the carbines to this day. The weapon was presented to public in April 1977 during Trade Fair exhibition at the Acconia Armoury stand. There is also a selective-fire model developed for military, capable of firing at 450–500 rpm.

Operation

The Hydrus semi-automatic carbine uses simple blowback action, firing from closed bolt. It features hammer-fired trigger mechanism with cross-bolt manual safety, located behind the trigger. Receiver and grip / trigger unit frame are made from steel stampings, grip itself is made from plastic. The Hydrus features fixed iron sights, top-folding shoulder stock and a short forend below the shrouded barrel. It uses double stack, double feed box magazines compatible with Israeli Uzi submachine guns.
