HK53

The HK53A3 is a submachine gun made by German firearms manufacturer Heckler & Koch. It is derived from the G3 assault rifle and bears a similar appearance to the MP5, because of its foregrip and retractable stock, but it is chambered in the 5.56x45mm NATO round and is fed from 40-round box magazines. It is featured in Battlefield 2: Euro Force and is set to appear in Battlefield 3: Back to Karkand.

Battlefield 2: Euro Force
The HK53A3 is the standard submachine gun issued to the EU Spec Ops kit. It has moderate firepower, low recoil, and a decent rate of fire. It comes with a 40-round magazine, and can be fired either full-auto or in mechanical bursts, though there is no difference in terms of accuracy between the two.
