Developed as the successor of the German Army’s MG3 general purpose machine gun. The mounting interface of the HK 121 is compatible with existing MG3 mounts and tripods already in service. The universal HK 121 can be used by dismounted infantry in the ground role, as well as for air defense or as a vehicle mounted/ coaxial machine gun. The HK121 shares several features with the 5.56 mm NATO HK MG4 light machine gun that was successfully adopted into German military service in 2005. The HK 121 machine gun is a gas-operated weapon, firing from an open bolt in automatic mode only. It has quick-detachable, air-cooled barrel, with a conventional rotary bolt locking function. The HK121 is belt fed, using standard NATO disintegrating belts with M13 links. The HK121 is fed from clip-on 50-round containers or separate belt boxes and is equipped with a pistol grip and rifle-type trigger. A variety of side-folding polymer buttstocks are available as well as a folding forend forward grip positioned under the gas tube. A conventional folding bipod is attached below the gas block, and the HK121 can an be installed on a wide variety of mounts and tripods.
