Edit: Sorry, guys! I managed to link to an unrelated video. It’s fixed now.
The Volksturmgewehr Gustloff (commonly and incorrectly called the VG1-5) was a last-ditch rifle developed by Germany at the end of World War II. Only a few thousand were made, and they did not make a significant impact on the war. The rifle was intended to are the Volksturm, the German equivalent of the Home Guard – basically old men and children. It was semiauto only and chambered for the 7.92×33 Kurz cartridge used in the MP44/StG44 (it also used the MP44/StG44 magazine). Mechanically, the Gustloff is somewhere between a direct blowback and delayed blowback design. It has a delaying feature which we will discuss in the video, but the gun works equally well without it.
We were fortunate to have the opportunity to shoot and disassemble a Gustloff VG1-5 recently and debunk one of the common internet beliefs about the gun. Enjoy the video!
