Heckler & Koch MPK-2020 SMG

Heckler & Koch MPK-2020 SMG is submachine gun descendant of the MPS and the G3 assault rifle. About five years ago, special forces units in Europe were looking for a replacement for their main short-range assault weapons. After detailed discussion with such units as GSG-9, the SAS, GIGN and Corporate strike teams like Dieter Kaufmann's Taktischekampf Einheit O, H&K produced a caseless 12mm laser- or smartchipped assault carbine. Slightly longer than the MPS, the MPK 2020 is compact enough to be carried in a thigh or long shoulder holster. Its 60-round magazine is deemed large enough for an initial attack without having to worry about reloading. Uncommon outside of Europe, this weapon is now a mainstay of anti-terrorist and special forces units in the EuroTheater.
