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
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

worldwide. It saw action during numerous military conflicts. This
weapon is still in service with more than 60 countries. So actually
