Yeah my SKS was having this problem. I eventually just said screw it and stripped it clean and put on my own stain. Turned out mighty fine.
I did the same. I bought one of the $100 Mosins that turned out to be not a great rifle (broken small metal parts on stock, dark bore and a badly pitted receiver blued over) so I stripped it bare and put a few coats of Watco medium walnut oil on it. It is a far better finish than what was on it and this was no collector's dream anyway.
