The MP55 is a German selective-fire, magazine-fed, 10mm submachine gun. It fires up to 30 10mm cartridges from the 30Rnd MP55 10mm magazine.
The MP55 features a solid, fixed stock, and Navy trigger group with a fire mode selector, giving users the option to switch between Semi and Rapid (semi and fully automatic, respectively) fire.
The weapon model also features a dedicated forend for a weapon flashlight, and a claw lock-on scope mounts on the top of the barrel/receiver group, although these appear to be purely cosmetic, and unusable.
The MP55 features 3 attachment slot:
- Barrel end
- Optical attachments
- The MP55 is based on the Heckler & Koch MP5/10, chambered in 10mm Auto
- The design of the MP55 is more akin to that of the MP5A2 with a Navy trigger group
- The MP55 uses the standard curved metal magazine, instead of a straight synthetic magazine designed for use with the 10mm Auto and/or .40 S&W cartridges
- The MP55 was added to the game in Update #50
