Power Surge,
Thanks for the reassurance about the off-center front sight. That is certainly odd that all of them ended up off to the left!
Likemeasks,
I appreciate the advice on future buys. I did not want one that had a tactical stock or other modifications, I was afraid of buying someone else's errors. I wanted to stick to as original a gun as possible. The one I have seems pretty good, but one or two parts don't quite match the rest. The gas piston on mine has some corrosion on the shaft, which seems out of place, being noticeably worse than the rest of the gun. It doesn't seem to affect function, so I cleaned it up a bit and left it. The cleaning rod and bayonet seem a bit too nice to match as original, but that's not a problem, just maybe not the parts it came from the factory with. I did see that the cleaning kit was an SKS type, not an AK type like I have seen on some others. Overall, I am happy. It works fine. I have learned a lot from reading all the topics here. Plenty of good advice so maybe I won't make a mistake on the next one.
Greasemonkey,
I agree about the over-cleaning. It can be worse than infrequent cleaning. I am a little guilty here, I like to clean a gun after shooting, but it doesn't really need it every 50 or 100 rounds, unless you shoot corrosive ammo, or plan to store it for a long time. I have resisted the urge to clean mine yet, but it hasn't been easy. I hope to shoot again this weekend, and I will certainly have to clean it then.
