well, I got my new stock in last week, and spent about 2 hours using medium-fine steel wool to sand the factory finish off because I didn't want to get rid of the knicks and character, just take the rest of the already flaking off finish down to wood. Once I got all that off, I liberally applied a couple coats of Tung oil, letting it soak in between coats until I was happy with the color and look.
I let it dry for 2 days, wiped it down, then cleaned my sks from previous trip to the range, and tried to put the wood stock on... Well, appraently, a Russian sks stock from a spike bayonet gun will not work on a Chinese SKS with a blade bayonet... the cross bolt was about 3/32 too far back and too high in the stock, and obviosly the slot for the bayonet is wrong, which I knew already... I spend a fair amount of time trying to wiggle the action into the stock, and it was rocking on the cross bolt.
so now I have a cool battle worn looking refinished wood SKS stock I'm selling, and the search for a more-correct wood stock for my rifle continues
