Locking is provided by two frontal lugs which lock into the steel insert pinned inside the stamped steel receiver. The VG 2 rifle is fed from detachable box magazines, originally developed for Gewehr 43. The stock is crudely made from wood and consists of two separate parts: shoulder stock with semi-pistol grip and fore-end. Wood parts are permanently pinned to the receiver. Non-adjustable iron sights are provided for close-range shooting only, and zeroed for . The Steyr Volkssturmgewehr VG 5 rifle (or more correctly, the Volkssturmkarabiner VK 98) was slightly less basic. It used the Mauser Gewehr 98 type bolt action with rotary bolt, some of the early guns actually had serialised K98 bolts and/or receivers probably sourced from parts storages or rejected from main production for some reasons. Later guns had more parts produced specifically for VG5, these were standard K98 parts, but of very low quality, they were obviously distinguishable by virtually lacking any finish. The barrels were actually all K98 standard barrels. It had an internal magazine, just like K98, though with simpler unremovable bottom plate, very basic unadjustable fixed sights and very simple short stock, making it indeed a simplified and low quality sporter stocked K98. These rifle prototypes were developed as part of the Volkssturm-Mehrladegewehr ("People's Assault Repeating Rifle") program. The Gustloff Volkssturmgewehr was designed by Karl Barnitzke of the Gustloff-Werke for the "Primitiv-Waffen-Programm" ("primitive weapons program") in 1944 and was intended to be used by the "Volkssturm". Production of the Gustloff Volkssturmgewehr occurred from January 1945 till the end of the war; roughly 10,000 were made. This gun was initially called MP 507. The MP 508 was fairly similar except it had a semi-pistol grip stock. The weapon employed the same 7.92×33mm Kurz intermediate cartridge as the earlier StG 44 assault rifle and also used the same detachable 30-round box magazine. The Gustloff Volkssturmgewehr uses a gas-delayed blowback action based on the Barnitzke system, whereby gas bled from the barrel near the chamber creates resistance to the rearward impulse of the operating parts, which ceases when the projectile leaves the muzzle, allowing the operating parts to be forced rearward by the residual pressure of the cartridge case.
