The Gustloff Volkssturmgewehr (originally called the MP 507, often erroneously known as the VG1-5) is a last-ditch semi-automatic rifle made by Nazi Germany.
The gun was designed by Karl Barnitzke of the Gustloff-Werke, and was intended to be used by the Volkssturm. Production started in January 1945 and lasted until the end of the war; roughly 10,000 were made.
The Gustloff Volkssturmgewehr used a unique gas-delayed blowback system, which was very similar to the one used on the Grossfuss Sturmgewehr. However, the Gustloff Volkssturmgewehr's gas system did not work as reliably as the Grossfuss', due to the gun's crude design.
- MP 507
The standard semi-automatic weapon. Its most distinguishable features are the stock which is also used as grip, the longer barrel and the lack of foregrip on the handguard. This is the more common variant.
- MP 508
Same as the MP 507, but with a semi-pistol grip stock. A select-fire variant also is purported to exist. Only one image of the MP 508 is known to exist and it shows it with a foregrip and shorter barrel.
- The Gustloff Volkssturmgewehr is featured in Fallout 4 as the "Radium Rifle". It is a hybrid as it has the stock of the MP 508 and the longer barrel and handguard of the MP 507.
- The MP 507 variant is featured in Call of Duty: WWII. It is depicted as fully automatic instead of semi automatic; the existence of such a version in reality is disputed. The "extended magazine" attachment gives it a fictional drum which is a modified and thicker PPSh-41 drum magazine.
