I have a guy that wants to trade me his Norinco SKS with 3 stocks (wood, tupperware and tupperware with folding stock) 5 mags of various capacity and 500 rounds of steel case ammo. I would be trading my FNH FNX9 with 5 mags. I just picked up a new SA XDM9 5.25" to replace the FNX for USPSA competition. I have never owned an SKS but shot one years ago. This would be a range toy more than anything or might be further traded. Is this a fair trade?
