The StG 45: Roller-Delayed Blowback StG 44

    A design that truly could have changed the war, the StG 45 was not completed until 1945. Designed to replace the StG 44, which was expensive and time-consuming to produce, the StG 45 was the result of a cost-reduction and mechanical simplification development. To meet the requirements of the war, the gas system was removed and roller-delayed blowback was introduced, alone with the fluted chamber to assist in extraction.

    The technicians that worked on the rifle ultimately would go on to influence many post-war rifles and the CETME was introduced with the same roller system. Ultimately, Heckler & Koch would purchase a license for the design which became the G3 and served as the mechanical basis of the ubiqutous MP5.
