This PDF is for a Sports SKS Semi Automatic Firearm Manual.
The SKS has a conventional layout, with a wooden stock and rifle grip. It is a gas-operated rifle that has a spring-loaded bolt carrier and a gas piston rod that work to unlock and cycle the action via gas pressure exerting pressure against them. The bolt is locked to contain the pressure of ignition at the moment of firing by tilting downwards at its rear and being held by a lug pressed into the receiver. At the moment of firing, the bolt carrier is pushed rearwards, which causes it to lift the bolt, unlocking it, and allowing it to be carried rearwards against a spring. This allows the fired case to be ejected and a new round from the magazine to be carried into the chamber.
The SKS’s ten-round internal box magazine can be loaded either by hand or from a stripper clip. Cartridges stored in the magazine can be removed by pulling back on a latch located forward of the trigger guard (thus opening the “floor” of the magazine and allowing the rounds to fall out). In typical military use the stripper clips are disposable. If necessary they can be reloaded multiple times and reused.
