   In the mid 1950s German MoD was looking for a new automatic rifle, chambered for a standard NATO 7.62x51 mm round. A number of designs were considered and the Spanish CETME Model B was eventually selected. In 1957 German government acquired production license of this weapon and handed it over to their Heckler & Koch (HK) company. After some local modifications this weapon was adopted by the German armed forces (Bundeswehr) in 1959 as a standard issue infantry rifle. It was used until the mid 1990s, when it was replaced by the G36 assault rifle. Production in Germany ceased only in 2001. Some variants of the G3 are still used by the German border guards and police forces. A large number of these rifles are kept in storage. The German G3 battle rifle was widely exported. At some point it was used by more than 75 countries worldwide. It saw action during numerous military conflicts. This weapon is still in service with more than 60 countries. So actually the G3 is as popular as the Russian AK-47 or American M16. In some countries it is still used as a standard issue infantry weapon. However numbers of the G3 are gradually reducing, as it is being replaced by modern designs. Currently the HK company proposes its new HK417 battle rifle, which can be seen as a follow-on to for the venerable G3.

   The HK G3 was, or still is produced in Bangladesh, France, Greece, Iran, Luxembourg, Mexico, Nigeria, Norway (AG-3), Portugal, Saudi Arabia, Sudan, Sweden (Ak 4), Turkey and the United Kingdom. There are numerous derivatives of the basic G3.

   Design of the G3 can trace its origins to the final years of World War II. This weapon is chambered for a standard NATO 7.62x51 mm (.308 Win) ammunition. It employs a roller-delayed blowback operating system. The G3 proved to be a successful and reliable design. This weapon is also easy to maintain. The G3 is cheap in production, as it uses a number of stamped steel parts.

   The G3 is capable of semi-auto or full-auto firing. Fire mode selector is conveniently located over the pistol grip and has a safety setting.

   This assault rifle is fed from 20-round capacity magazines. It is also compatible with a 50-round drum magazine.

   Early production versions of the G3 have simple iron sights. Later these were replaced by diopter-type sights. The rear sight post has a rotating drum with range settings for 100, 200, 300 and 400 meters. Furthermore this automatic rifle can be fitted with scopes or night sights.

   First production version of the G3 had a fixed wooden buttstock. Newer models have plastic buttstocks. Also there are versions with a telescopic metal stocks.

   This weapon can launch riffle grenades. Furthermore it is compatible with HK79 40-mm underbarrel grenade launcher. This automatic rifle can mount other accessories, such as silencer or bayonet. Later production models can be fitted with a bipod.
