The SKS was developed at the end of World War II and, contrary to what most people think, actually saw very limited service in the final stages of the Eastern Front. However, while the SKS may have been meant to replace the Mosin Nagant as the standard issue infantry rifle of the Soviet Union, it was ultimately overshadowed by the AK-47 rifle instead. The SKS is a semi-automatic rifle that fires the 7.62x39mm round (the same round as the AK-47 with ballistics similar to a .30-30) and is located via a stripper clip in the top of the receiver. The SKS was designed to be a shorter rifle firing an intermediate cartridge with a faster rate of fire than the Mosin Nagant, but the fact that the AK-47 had greater capacity and a detachable box magazine are what ultimately caused it to be adopted instead. Nonetheless, the SKS was adopted in limited use by the Soviet Union and was sold in mass quantities to Communist countries through the Cold War. Today, it’s a common military surplus weapon in the United States.
