Lampwick, I don't have any but was wondering if you know if you or I could build a semi out of a parts kit using a pistol parts. And why hasen't anyone made 80% recievers for this gun? Was wondering if you knew offhand. It sounded like you are an enthusiast of this model...Slowfinger
The only all metal one that I have been able to lay hands on is a Tanaka Airsoft WZ-63 which I have modified . This is the same weight and size as the original and the only give away was the small nozzle on the underside of the magazine.
