The German FG-42 paratroop rifle was a very impressive design, managing to meet a very strict set of performance criteria. The first production model in particular was exceptionally light and compact, while still offering semi and full-auto 8mm Mauser fire with surprisingly light recoil. The gun went through a continuous evolution through its production, becoming heavier and less expensive to manufacture. The first major design was made from a milled billet of steel at great cost, and the second major model was done with a stamped steel receiver instead. We had the opportunity to disassemble one of the second model FG42s, and put together a video showing how it operates.
