Out of curiosity, is the stock cut to accommodate both blade and spike bayonets?
$600 is a phenomenal deal.
That would be the deal sealer.
I have one like that, in the 12 million range, blued bolt, double cut bayo slot, but with a closer matching HG. Those Russian laminate stocks are nice.
It was my first SKS actually, $70 bucks, single shot. The gas piston was stuck in the tube.
