SKS, or Samozaryadny Karabin sistemy Simonova, is a semi-automatic rifle developed in the Soviet Union during World War II. Designed by Sergei Simonov, it was officially adopted by the Soviet military in 1949. The SKS is chambered for the 7.62x39mm cartridge, which provides a balance of power and manageable recoil, making it effective for various combat situations. The rifle features a gas-operated action and a fixed magazine that holds ten rounds. Its design includes a wooden stock and a distinctive bayonet, which can be attached for close combat. The SKS has been used by many countries and remains popular among collectors and shooting enthusiasts today.
