I just bought a Chinese SKS and I am in the middle of tearing her down for cleaning. After following the instructions on surplusrifle, I found that when I removed the handguard, the gas piston and spring did not eject on me. It seems to be stuck inside the tube/handguard. Is it that dirty in there? What should I do to remove it? Gun oil? Penetrating oil?
