MG5 - Germany’s Modern Machine Gun

Summary

The Heckler & Koch MG5, also known as HK121, is Germany's modern 7.62x51mm NATO general-purpose machine gun, developed to replace the venerable MG3 in Bundeswehr service. It features a gas-operated rotating bolt system, improved modularity for various barrel lengths and optics, and a more controlled rate of fire between 640 to 800 rounds per minute, unlike the MG3's higher cyclic rate.
