The HIW VSK was a carbine of German origin developed by Hessische Industrie Werke. It was intended as a Volkssturm weapon and used blow forward operation.
The weapon uses a blow-forward action with a movable barrel. Ammo is stored in a non-removable box magazine which holds 5 rounds. The rifle's action is similar to that of a double-action revolver. Pulling the trigger causes the hammer to drop, causing the bolt to unlock and push the barrel forward. When the barrel is blown forward, the gas pressure is high. When the pressure of the gases come back down to atmospheric pressure, the barrel returns to its rear position; this activates the ejector, ejecting the cartridge and causing a new cartridge to be loaded into the weapon. The barrel jacket has holes in it to cool the barrel, while the barrel has polygonal rifling.
