The Harman MP-50 is fully automatic, equipped with a scope. This weapon is carried by the Volk and the Shai-Gen. Due to its scope, it can actually be used at long range more easily than the Ingalls MG-60 Assault Rifle, and is actually more comparable to the Colby EAR50 than other sub-machine guns or the MG-60.

It seems to represent the Heckler & Koch MP5K.
