It was invented in the 1950s, and was the main weapon of the German army (Bundeswehr). Now the main weapon is the G36. Many German soldiers want the old G3 back. The G3 is still in service as a sniper rifle,[source?] but they changed to the G28 for "designated marksmen".

The deign of the G3 was so influential that it was the base for making the MP5 and the PSG-1.
