The M5K appears in Battlefield Play4Free as a purchasable SMG for the Engineer class. M5K has 4 24-round magazines, 3-round burst fire mode, and rate fire of 1200 RPM, which makes short work of any enemy at close quarters. This weapon is very compact, so reloading and ADS time are very fast. Also, it is the only weapon with burst-fire capability for engineer class.
