The Volkssturmgewehr 1-5 ("People's Assault Rifle") is a set of 5 rifle designs developed by Nazi Germany during the last months of World War II. They were very simple designs, derived from the Mauser 98k, but with poor quality parts and a rough finish. There is confusion concerning the designation, sources talk about the VG 1-5, the Volkssturm-Gewehr 1-5, Versuchs-Gerät 1-5, Gustloff and Gustloff Geräts 507. It is often believed that the VG 1-5 refers to a specific type, usually the Gustloff design, a semi-automatic rifle chambered for the 7.92x33mm Kurz caliber. This was however another type of weapon though may also have been a part of the same program.
