The ALKA model 93 is one of the nicest of the several dozen simple SMGs made in Croatia during the Homeland War of the 1990s. It was produced by the IM Metal company (later renamed HS Produkt) starting in 1991, was formally adopted by the Croatian armed forces in 1993, and produced until 1994 or 1995. Several thousand were made in total, although I have not been able to find an exact number.

Mechanically, the Alka is a hybrid of the Ingram M10/M11 and the Czech vz.61 Skorpion. It is chambered for 9mm Parabellum and uses a telescoping bolt and recoil system copied directly from the Ingram. The bolt travel is quite short, and the rate of fire is quite high; approximately 1200 rpm. The receiver is a square tube made by folding flat sheet metal over a mantle and seam welding it together. The stock is copied directly from the vz.61, although it is longer and thus more comfortable to use. The magazine is a proprietary single-feed type, but again clearly copied from the MP40.

Thanks to HS Produkt in Croatia for inviting me into their factory and providing this example of the Alka for me to film!
