Zachary Levi's tranq gun from Chuck?

[Burnt]

Being a huge fan of the show since day one, I would love to know about this prop. I know what it is made out of and all that but I really want to know how much it sold for and who bought it. Being a fan boy of the series I have to know where this thing is and maybe in the future get my hands a hold of it with COA hopefully. Thanks
