In todays market maybe. I love my SKS and while I am sure you could sell it, if it just sits in the safe and the 642 gets use maybe not. Seems as things go the SKS may be one of those weapons that becomes REALLY valuable one dayif these fools in office get their way.
See how I didn't really answer the question? I should run for office! Trade it if you dont use the 642. If you or your Mrs carry it, keep it.
