More Information ^*

The HK 21 is a belt-fed general purpose machine gun using the 7.62 x 51 mm NATO cartridge. The method of operation of the HK 21 is the same as that used in the G3 rifle), employing a two-part breech block and delay rollers. The delayed blowback system, with a fluted chamber for easy cartridge movement, operates from the closed bolt position with a round in the chamber when the gun is ready to fire. Ammunition for HK 21 usually is carried in the disintegrating link belt and the gun will function using either the German DM 60 belt, the US M13 belt or the French belt. However, the continuous link belt DM 1, can also be used if required. Furthermore, by changing the barrel, the belt feed plate and the bolt, the gun can be converted to firing the 5.56 x 45 mm or the 7.62 x 39 mm cartridge. The utility of the weapon is further increased by inserting a magazine adaptor in place of the feed mechanism. This takes any of the Heckler and Koch 7.62 mm magazines intended for the G3 rifle or the HK 11 light machine gun. If required, the belt feed unit can be withdrawn and replaced with a magazine unit which fits into the receiver and is held by two locking pins. The unit allows the use of the 20-round box magazine or the 80-round double-drum plastic magazine. The gun may be fired at single shot or full automatic. The selector lever is above the pistol-grip and the trigger mechanism, disconnector and automatic sear are the same as those used in the G3 rifle.
