The Heckler & Koch UMP (Universale Maschinenpistole, German for "Universal Machine Pistol") is a submachine gun developed and manufactured by Heckler & Koch. Heckler & Koch developed the UMP as a lighter and cheaper successor to the MP5, though both remain in production. [4]

The HK UMP is freely configurable with regard to its features. The optional equipment portfolio ranges from the classic skeleton buttstock to the use of tactical helmet buttstock variants. The UMP is available as a semi-automatic or fully automatic submachine gun.
