Has anyone ever seen one like this? A customer brought it to me as a consignment and I've never seen one like this. He purchased it new with the red controls from another local dealer. I have no reason to not believe him when he says that its a factory rifle but because I haven't seen another, I don't know quite what to make of it. Pics are in the link.
