I have been looking at getting a SKS rifle. There is one I am looking at that looks to be in good condition, its a Chinese norinco and has 2 30rd detachable magazines but doesn't have the original 10rd fixed mag. Is there any modifications done to use the 30rd mags? I want a stock SKS so I will have to find a 10rd mag. It is also missing the bayonet but has the bayonet lug so I will have to find a bayonet. he is asking $400 obo. I might try to offer $300 or $350. does this sound like a good deal?
