ATI SKS Traditional Stocks
This is just my opinion, but resist the urge to "tacti-cool" it out. SKS's usually run best off stripper clips, with a fixed mag. I have seen a perfectly reliable sks get all bubba'd up by somebody wanting to put a detachable mag on it, and then it becomes a jam-o-matic. You could replace the stock with one like above, and then get a bunch of stripper clips, and become proficient in their use, and have a fine SHTF rifle.
