Proud to have some of my work in PUBG. The UMP is one of the sub machine guns that can be used in Player Unknown's Battlegrounds.
On the top screenshot you'll see them using a different scope and silencer but the main UMP is from my weapons pack.
This model can be purchased at the following stores:
