There is usually a pin that looks like a rivet. You need to probably soak this in oil and then beat the crap out of the pin with a punch. On my SKS, I upgraded to the TAPCO stock, and simply changed the gas tube and piston and springs, along with the stock, to make it compliant. The new gas tubes need to be filed down a bit to fit snugly, but other than that they work great.
BTW, AKs are much easier to remove because they simply rotate off. The SKS looks similar, but does not function the same way.

If that doesn't work, get a bigger hammer.
