The HK UMP ("Universale Maschinenpistole" in German) is a machine gun manufactured by the German firm Heckler & Koch and put on sale from 1999, primarily designed for the North American police market with the ambition of replacing the MP5.
Few months ago, HLF started to sell UMP45 nylon receiver for Gen8. With your powerful gen8 nylon gearbox used in some other models, we decided to created the best UMP45 available on the market.
That's how this model was born. A UMP45 able to pull up to 280 fps.
