HK MP5 Series, HK MP5K-PDW and HK MP5SD Submachine Guns

Developed by Heckler & Koch in the mid-1960s, the 9 mm MP5 submachine gun uses the same delayed blowback operating system found on the famous HK G3 automatic rifle.

Firing from the closed-bolt position in all modes of fire make MP5 submachine guns extremely accurate and controllable. All HK MP5 models are manufactured using time-tested Heckler & Koch technological invocation and superior materials. Barrels are made using cold hammer forging, a process pioneered and perfected by HK.
