The MP5 is a german SMG known for its tested and reliable design. Its most commonly seen on "good guys" in action movies and that might be the same in real life also. The MP in its name stands for maschinenpistole as it is a gun that shoots pistol calibers at fast rates. Its reciever has many variations such as the HK53, basically a 5.56x45 version of the MP5, the MP5A2 with a collapsable stock, and the MP5/10 which shoots the powerful 10mm auto round. If you wanted the best, you bought german. #gunfacts
