Historical profile
Developed after World War II from lessons learned from the German MG 42 and earlier Swiss systems, it was adopted as the new standard machine gun of the Swiss Army in 1951.
Renowned for strength, accuracy and excellent workmanship, it used the powerful GP11 cartridge but was also notably heavy compared with other contemporary GPMGs.
It served for decades as a squad, support and static weapon before being gradually complemented or replaced in specific roles by lighter systems such as the FN Minimi and later Swiss machine guns.
