The H&K G3, a descendant of the Nazi STG-45, became a cornerstone of Western defense during the Cold War. Its roller-delayed blowback system, while sensitive to pressure, offers a cleaner operation than gas pistons. Despite its battle rifle role, it demonstrates controllable recoil and acceptable accuracy for its intended range.

This video details the incredible 'Mauser Train' evacuation of R&D assets at the end of WWII. It highlights the logistical challenges, including moving 29 boxcars of material by truck and bicycle, and the perilous journey involving air attacks. The story culminates in the discovery of the train by Allied forces and the eventual fate of its valuable prototypes, including the StG 45.

The roller delayed blowback system, originating from Mauser's WWII experiments, uses angled surfaces on a locking piece to delay bolt carrier rearward movement via rollers. This design allows for mechanical simplicity, compatibility with stamped receivers, and high accuracy due to fixed barrels, but can be prone to fouling and has issues with suppressors. Firearms like the G3 and CETME utilize this operating principle.
