That is pretty much what I have found for new. The guy doesn't know what it is worth. He is asking $1300. But is willing to negotiate. I was wondering what they are going for used.
Condition matters, of course.
If it is like new, with very few rounds and no nicks or scratches, then $1200-$1250 seems reasonable. Anything more and just buy a new one anyway.
Lesser condition = less value.
