H&K USC: Civilian Version of the UMP Submachine Gun
This video provides an overview of the Heckler & Koch USC, the civilian, semi-automatic variant of the UMP submachine gun. It details the USC's design, its polymer construction, and its hammer-fired, closed-bolt operation. The description highlights key differences from the military UMP, including a restricted magazine well, a thumbhole stock, and a longer barrel, suggesting that many USC owners modify their firearms to resemble the UMP. The video also touches on the UMP's development as a successor to the MP5 and its focus on American law enforcement.
