The MP5K (Kurz) is the ultra-compact variant of the MP5, eliminating the stock and shortening the barrel to 4.53 inches for maximum concealability. Designed for protective details, vehicle crews, and rapid-deployment scenarios where even the standard MP5 is too large. The roller-delayed blowback mechanism is unchanged. In semi-automatic form, it qualifies as a pistol. Widely used by European close-protection units.
