So I received the chinese sks finally today. It had 5% of the cosmo that russian had so so far cleaning is a breeze. Some comrade somewhere did all the dirty work in my place, go figure. It also came with what appears to be a fiberglass 'jungle' stock. I never even knew that these things existed before researching it today. That was a VERY cool surprise.
The receiver and barrel have great 90% blueing. I can't complain there at all. The bore looks very clean. The downside is some parts are very varied from pristine (trigger group) to pitted (main piston). I can't really complain at the price that I paid. Should a rifle still be serviceable with pitted piston?
It also has the needle bayonet, not the screw-driver spike I'm used to seeing. I'm not sure what to make out of that.
Never heard of a needle bayonet. Can you post a picture?
