The weapons HK 33 E and HK 53, cal 5.56mm x 45 (.223) are modern combat rifles, produced in accordance with the most advanced manufacturing methods. From closed bolt position this weapons permit the firing of single shots and bursts from all shooting positions. Both weapons are recoil-operated with stationary barrel, incorporating a roller locked delayed locking system and are fed from a 25 round magazine.

The weapons HK 33E and HK 53 are largely of identical design and construction. The only differing design features refer to barrel length and handguard. Due to the very short barrel length, the HK 53 can be employed as a submachine gun.

Handling and operating of both weapons are identical.

DESCRIPTION OF THE ASSEMBLY GROUPS

Assembly 1 Receiver and barrel, cocking mechanism and sights

The receiver connects barrel, cocking mechanism and sights. All major assemblies are housed within or attached to that group (Fig. 7).

The barrel is a press fit in the barrel extension and is pinned. The threaded muzzle receives a flash suppressor which also serves as a grenade launcher. The cocking mechanism is arranged above the barrel. It is used for manual operation of the action and to arrest the bolt in rear position.

The sighting device consists of a front sight and a rotary rear sight. This rotary rear sight is provided with 3 aperture positions and 1 open "V" sight and may be set for a range of 200, 300, and 400 meters.

The rotary rear sight can be adjusted for elevation and windage.
