Just had a friend stop by and I bought a chinese sks for a $150. I figured I can't go wrong for that price. I however don't know anything about sks's. Please educate me on the SKS. It has chinese markings with a a triangle marking that looks like a number 606 in it. The stock is heavily worn, but the mechanics seems sound. The bolt will hold back with an empty clip, but will slam shut as soon as I remove the clip. Is this normal. Also I cannot get a new clip to seat unless I hold back the bolt. Is this normal. Shouldn't the bolt hold back to receive a new clip? Can someone tell me about this. Thanks in advance.
