- "Close range 9mm submachine gun with a high rate of fire."
— In-game description
The MP5K is functionally similar to its full-sized cousin. Like the MP5, attaching a Suppressor has a near negligible difference in close-quarters due to its high RPM.
- In Mute's Operator Video, he is holding an MP5K that has an ACOG attached to it, despite the fact that that this telescopic sight is not available for it in the actual game.
- In certain stills involving Mute wielding the MP5K, the submachine gun is equipped with a Compensator.
- In the still for the Teal Universal Color Skin, the MP5K is equipped with a Reflex Sight and a Compensator.
