The basic action of the machine gun, which received the company designation HK 21, was similar to that of the G3 rifle. The HK 21 fired from a closed bolt (not that big issue since its heavy barrel was really quick-detachable) and, unlike most machine guns, its belt feeding module was located below the receiver. Variants: HK11E automatic rifle (magazine fed, 7.62 mm) HK13E automatic rifle (magazine fed, 5.56 mm) HK21E general purpose machine gun (belt feed, 7.62 mm) HK23E light machine gun (belt-fed, 5.56 mm). The "E" stands for "Export" model.

Global distribution list
The data on global distribution and production is provided primarily by the BwVC, but also from national and regional focal points on SALW control; data published by think tanks, international organizations and experts; and/or data provided by individual researchers on SALW. It is not exhaustive. If you would like to add to or amend the data, please click here.
|Country of origin|
|Production without a licence|
|G||Government: Sources indicate that this type of weapon is held by Governmental agencies.|
|N||Non-Government: Sources indicate that this type of weapon is held by non-Governmental armed groups.|
|U||Unspecified: Sources indicate that this type of weapon is found in the country, but do not specify whether it is held by Governmental agencies or non-Governmental armed groups.|
It is entirely possible to have a combination of tags beside each country. For example, if country X is tagged with a G and a U, it means that at least one source of data identifies Governmental agencies as holders of weapon type Y, and at least one other source confirms the presence of the weapon in country X without specifying who holds it.
