    This is what was lurking below the wood...

    Concerns?

    It’s a Chinese, mid-sixties serial.

    Concerns? I wouldn't be concerned or worried about it. The wood gave up moisture and it rusted a little causing pitting. Unusual that there is no orange coloring rust. Anyway, there is nothing there which will affect form, fit or function of the rifle. Light coat of oil and put it back together. I have seen much, much worse. On the bright side it is a full lug threaded barrel and not the later press fit pinned type. :)

    That pitting is old enough that the Chinese gave it a blue over during their refurb for sales to civilian market,
    I wouldn't think it was a problem

    That would explain it.

    Put some RIG on the metal under the stock and forget about it.

    Looks better than most of the ones I found overseas.

    Yes, it’s a refurb.

    They brought it in from work for a fix, the security guard who had it found it weird that upon cocking, the gun would go Rat-taa-taa-taa-taa without anyone even pulling the trigger... :D

    Never really been interested in SKS, until I had to take this one apart. Neat lil’ rifle! Built like a tank, looks like you won’t be able to break one if you try. Simple, rugged, made for a rough life. I proceeded to select one that I’m going to build up the way I like (not this one...).

    sounds like the firing pin wedged into the firing pin block in the forward position, effectivly making it an open bolt machinegun. it's a simple fix of replacing the firing pin and firing pin retaining pin. I really like the sks. pity they cost more than a cheap AR now.

    the firing pin can get stuck with alot of shooting without cleaning, the will run pretty fast.

    the norinco I had just had soft metal and that wore in such a way that the stop on the firing pin wore away and allowed the pin to wedge in a forward position as it interfaced with the firing pin stop pin. I've also had some issued with dirty pins. as long as you are in the gun, you might as well fix the trigger.

    Firing pin was stuck (corrosion), hammer was following (negative sear interface), and bolt was not holding open on last round (nimble hands loaded more than the allotted five rounds from the bottom of the open mag - it’s a 10 rounds mag pinned to five - and cheerfully proceeded to crush the follower arm while trying to stomp the mag into submission).

    All fixed and working now.
