The HK53 is a compact assault rifle of German origin. The HK53 is the short carbine variant of the HK33 rifle. It is often classified as a submachine gun due to its compact size. The HK 53 looks like it has similar proportions as the MP5, but the magazine well and forearm, and flash hider are longer, making it a slightly longer weapon.
The flash hider is longer and of a four-prong design while the flash from such a short barrel is much larger. Virtually all HK53 are fitted with a retractable stock, making them the HK53A3. It is possible to fit fixed stock, resulting in the HK 53A2. During its production life, the HK53 received upgrades similar to the HK33E such as a new retractable stock and a new flash hider but was never rebranded.
