The SG-43 Goryunov was a Soviet medium machine gun that was introduced during the Second World War. It was chambered for the 7.62×54mmR cartridge, and was introduced in 1943 as a replacement for the older M1910 Maxim machine guns. It was mounted on wheeled mounts, tripods and armored vehicles.After the end of World War II, the SG-43 was improved and renamed SGM ("M" for modernized); dust covers and a new barrel lock were fitted, and a splined barrel was fitted to improve cooling. A tank mounted variant was also developed under the designation SGMT.
