I've been watching these at j&g and missed out on buying the unissued ones that were in real nice shape, they were selling them for $225 when they had them.
I've also seem the ammo sell online for $250 a case if you can find it. Add it up $225 for the gun, $250 x 2 for the ammo, its close to the going price on the current market. I'm sure the guy could easily get, $250 a case if he separated it.
