You ever seen a North Vietnamese SKS? They only came back into this country as bringbacks from Viet Nam. They are incredibly rare. They go for $5,000+ on gunbroker. The other super rare SKS are the East German and the North Korean.
Never paid attention to them, like I said I know diddly squat about them but I guess like everything there's rare versions of most stuff that sell for way more than most people would realize.
I've heard stories of people getting a free SKS back in the day (90s) when you'd buy a crate of ammo...so they always sounded pretty plentiful and inexpensive.
Anywho, sounds like an opportunity to make a few bucks on a quick flip!
