the sks is only worth $225 in its current state, i'd go with the mosin it being a sniper but if its a repo sniper its only a $425 rifle but is worth more than the sks. either way as far as a higher value the mosin would be my first choice but semi-autos are much funner. i say get the mosin, think about this... how many sks' are on the shelves at the local gun shops? now how many mosin snipers do you come across?
