The Heckler and Koch MP5 is a series of German delayed blowback, selective fire sub-machine-guns developed from the G3rifle, introduced in 1965 and adopted in 1966 by the West German police and border police. The weapons are chambered for the 9 mm Parabellum cartridge and are fed by a 15- or 30-round box magazine and have a cyclic rate of 650 rounds-per-minute, or selectable single-shot, with a muzzle velocity of 400 meters-per-second. The range includes silenced models and various stock options; none, telescopic and fixed. The MP5 range of sub-machine-guns have a 225 mm long barrel, fixed post foresight and aperture rearsight, and may also be fitted with a telescopic sight, night sight, or the 1003 aiming projector. For training, a .22 Long Rifle calibre conversion unit can be fitted. Research Heckler and Koch MP5
