The Gerat 03 was the first prototype roller-locked rifle developed by the Germans during WWII. Only a few were made, and the rifle was never put into mass production. This is the direct ancestor of the HK91 family of roller-delayed firearms.
At Forgotten Weapons I think the most interesting guns out there are the most obscure ones. I try to search out experimental and prototype weapons and show you how they work, in addition to more conventional guns that you may not have heard of before. You’re much more likely to find a video on the Cei Rigotti or Webley-Fosbery here than an AR or Glock. So, do you want to learn about something new today? Then stick around!
