Steyr-Solothurn S2-200: the Austrian MG30 and Hungarian 31M
The Steyr-Solothurn S2-200, known as the MG30 in Austria and 31M in Hungary, was a German-designed machine gun produced via Swiss and Austrian partnerships to circumvent post-WWI arms restrictions. Designed by Louis Stange, it featured a recoil-operated rotating collar lock and a slim profile due to lathe-turned parts. Adopted in 8x56mmR, it utilized a distinctive curved 25-round side magazine.
