3D Animation: How a H&K MP5 Submachine Gun works

The MP5 ("Maschinenpistole 5", german for "submachine gun 5") is a submachine gun chambered in 9x19mm Parabellum, designed and manufactured since 1964 by German gun manufacturer Heckler & Koch. The MP5 is one of the most widely used submachine guns in the world, having been adopted by 40 nations and numerous military, law enforcement, intelligence, and security organizations. The roller-delayed blowback mechanism originated from the aborted "StG 45" assault rifle prototypes developed in Germany at the end of World War II. 3D Animation done using:
