This video provides a detailed look at the German Gerat 03 prototype rifle, focusing on its unique roller-locked, gas-operated mechanism. It explains how the system, largely designed by mathematician Dr. Karl Mayer, adapts the Gewehr 43 platform. The disassembly focuses on the bolt, trunnion, and camming piece, illustrating the precise angles and roller engagement that achieve a locked breech. The video highlights the Gerat 03's significance as the precursor to modern roller-delayed blowback firearms like the H&K G3.
