Nice Type 56 SKS,
theSKSguy45! Great series in those years from /26\.
I'm not sure what caused the staining on your Bolt Carrier, although I've seen many like that. I've wondered how using a glass bead treatment would turn out. Regular sand blasting would be too course and change the original finish fairly drastically. I suppose it would depend on the depth of the staining as to how well that option would work. All this depends on your dedication to preserving the original finish and keeping it in "as-issued" configuration. If that's not a concern to you, then polishing it with a compound would take it to a higher gloss and remove the stain. As they say....It's your rifle....
The '78-'79 /26\ rifles are some of my favorites. I had a couple extra of them still new, unfired, in original boxes with the issued accessories that I sold last month a a local gun show. Both sold for $800.00 each, cash, without an argument. They didn't even try haggling. I'm continually being surprised at the appreciation in value that many of the SKS models have enjoyed. Out of curiosity, what are these costing folks north of the border now? (go ahead, make us jealous again.
)
P32,
Running Man, or
Greasemonkey may have a good answer for the cause of the staining.
They be smart! Actually, we have a
