Following the success of the HK G3- itself derived from the Spanish CETME- in the 1960s, Heckler and Koch began to experiment with multiple other roller-delayed firearms that followed the general design language of the G3. Born from this testing was the HK54, which would eventually evolve into the MP5 (Maschinenpistole 5).
Though HK declared the UMP the MP5's 'successor' when it was designed in 1999, the MP5 still remains in production, and is far more common than it's younger sibling.
In game, you can expect the MP5 to be a viable, stable option with a large ammo reserve to ensure you can keep spraying. Additionally, it should prove to be concealable enough for dodge and crit builds.
