I'm considering offering a trade and would like to see some opinions from you guys. I have a Yugo SKS, one of those that was never issued and never fired. It is beautiful but still full of cosmoline. All the numbers match except for the installed Chinese 20 round fixed magazine (a 10 round fixed mag is included). I have a bunch of Wolf Military Classic FMJ (non corrosive) 7.62x39 ammo for this (or an AK). I'd like to trade this SKS with some ammo (good quality clips included) for a Saiga Sporter unmodified. Any thoughts on the quantity of ammo to add to make this a fair trade? Other constructive comments are welcome. Thanks.
