Thanks for the replies guys. I thought $600 might be a bit high but figured if he asked that he could always come down on it. Maybe I'll have him start at $525 and come down if necessary. I'd like to buy the gun from him but it's not in my current budget so I'm just trying to figure out what it's worth for him. I'm sure if he can't find a buyer for it he'll make me a deal I can't refuse though.
