Development of the MG 30 took place under the direction of Louis Stange at Rheinmetall's Sömmerda office. Production soon followed, entering the armed forces of Germany and Switzerland as the Solothurn S2-100 and Maschinengewehr Solothurn 1930, or MG 30, respectively. 2000-3000 were also purchased by Hungary, where it was known as the Solothurn 31.M Golyószóró.
The MG 30 fired both in semi-automatic and full automatic mode depending on how far the two-stage trigger is pulled, with a rate of fire between 600 and 800 rounds per minute in full-auto. It included a folding bipod attached two thirds down the barrel.^
