The SKS was the second firearm to be chambered for the 7.62×39mm M43 round, with the first being the RPD.
The SKS has a conventional layout, with a wooden stock and rifle grip.
In common with some other Soviet-era designs, it trades some accuracy for ruggedness, reliability, ease of maintenance, ease of use, and low manufacturing cost.
The SKS is a Soviet semi-automatic carbine chambered for the 7.62×39mm round, designed in 1943 by Sergei Gavrilovich Simonov.In the early 1950s, the Soviets took the SKS carbine out of front-line service and replaced it with the AK-47; however, the SKS remained in second-line service for decades. The SKS was widely exported, and was also licensed for production by then Eastern Bloc nations, Romania and East Germany, as well as China, where it was designated the "Type 56 Carbine".
