The magazine is real, it is an aftermarket mag made by the Chinese for the then exploding SKS market in the US....they are known to feed somewhat unreliably, at least without modification....yet, they fetch a premium price now. $75-$100 prices are not unusual. The variants without the star tend to get more due to being less common. While I think they are fugly on a wood stocked SKS, I think they are acceptable on a black gun...at least in appearance. I can't bring myself to spend that much only to find out I indeed hate them.
I would pay $200 for that patina laden SKS...either to keep as is, if it was original, or make it shine again if it is a parts gun...if they got that bolt open, chances are the corrosion is only there to make it look mean.
That scout mounted scope looks like it needs a regular scope to view, but I have a LER Norinco scope that probably would work great that far away. If only it would hold still way out there...
I love the square nuts, it reminds me of having an Erector Set as a kid...
