What should do to check for proper operation when firing my SKS Carbine the first time?
When firing any semiautomatic firearm for the first time, always follow these safety procedures: Load two rounds into the magazine, and in a stable shooting position, with the muzzle pointed down range, pull the charging handle (or slide) back and let it fly forward to chamber the first round. Do not ease the carrier or the slide into battery. If the weapon fires, cease firing immediately. If no firing occurs, aim the weapon down range and pull the trigger. If both rounds fire with one pull of the trigger, cease firing immediately. These same procedures should also be followed anytime you are unsure if your ammunition uses “mil-spec” primers.
