As far as I know they only make Grey, Blue, and Black. I have a Blue P-70 but I think I would get the Grey. Hey what F-1 parts does Feinwerkbau make, and for whom?
Doc Beeman reports FWB in the Bluebook of Airguns (our host has 'em for sale) is making "top secret" parts for F-1 but doesn't reveal the parts or for what team ( perhaps _MW?).
Kind of like the black but guess no one cares what color for a $2,900 AF.
