I could double post what Terry said.Matter of fact when I showed interest in his, he point me to the auction for the one I now own.Wonder how the seller determined it's age. Says it's a first year model, while it is hard to tell from the pics, the end-cap looks like the later internal thread model like mine.Terry, yours is an early one, Can you tell?Wonder if he stored it all these years with a Co2 cart in it. They tend to get stuck, that is how I got my "minty-fresh" one so cheap. They are gas hogs, even worse that my 160, and they only hold 1 cart... but the later one can be converted to Bulk Fill.Yes, mine has a flat-top receiver and the vent hole way down just in front of the stock. Makes bulk fill problematic. I still like it, it's just as accurate as my C model.
Gotchya! The auction does say "Rifle has seen minimal use"Lord knows I sure would have a real rough time NOT shooting one if I stumbled across a NIB find.
