Prototype weapons of WW2
StG-45(M), final pre-production version of this German assault rifle in 7,92x33mm Kurz.

But it showed huge potential which combined with simplicity and low cost led to possibly replace StG-44. It was roller delayed blowback with rate of fire 450RPM. In its pre-production version it is said to be really reliable weapon. New 10 round magazine were developed with it. Some of 30 were made.

They selected the CETME as a pattern and their newly established company Heckler & Koch developed their own version - the G3 assault rifle so the design found its way back to Germany...
