9mm submachine gun of German design. The MP5 is one of the most widely used submachine guns in the world, it uses slightly curved, steel magazines with a 15-round capacity or a 30-round capacity. It has a hammer firing mechanism. The trigger group is housed inside an interchangeable polymer trigger module (with an integrated pistol grip).
A common misbelief is that the firearm and its magazines only spawn at Helicopter Crash Sites – this is incorrect, they can only be found inside military prisons, barracks, police station buildings, police cars, and in the newly added prison island. Look closely inside of the police stations, they may be hard to see and may spawn beneath books, under desks, behind crates, and in strange spots.
The MP5-K takes up a 4×3 space in your inventory. Most backpacks and the high capacity vests will allow you to carry it concealed, also allowing you to carry another primary weapon on your back. While the 12 inventory slots are quite a bit for such a compact gun, being able to carry two long arms is quite a good thing. Adding and removing attachments does not affect its size in inventory.
The MP5-K has a few attachments, which may commonly be found in military installations and buildings.
