When buying a used SKS from a gun shop or show what should I look for. Are there parts that wear really easy or what? There is one at a local shop that looks almost brand new in my opinion, it has no gashes in the wood and it has a blade not spike bayonet. I am truly unsure of the model besides it being an SKS. He is asking $275 for it. Is that too much? I have an H&R shotgun I am refinishing that I was gonna trade for it plus cash. What do y'all think?
