Hey guys. So this afternoon I bought my very first gun!!! wooo. Anyways it is a Norinco SKS. What I noticed after purchasing it is that the gas tube release lever thing was all the way up and front. I heard that this is bad apparently as something likely flew out of it, also I cannot remove the gas tube, it appears the back of it has rusted slightly and it is just a little too tight to wiggle it off, I am thinking either more muscle or more sweetly persuading it. Anyone have any thoughts to add? I won't be able to get out to see if it fires for a couple days at least.
