Hi FattMann, I have the Firebird and the Spitfire complete with extra barrels. You can fill from a buddy bottle but you can also fill from a divers bottle as per a standard pcp. These rifles are supremely accurate especially the Firebird with fixed barrel, I shoot mine at small targets (about 75mm) at 70 metres getting continuous hits. These rifles orignally got bad press for leaking air. The reason is they should not be stored for long periods of time without being used. As long as you fire and top up the air once every couple of weeks you should have no problem. They are also very easy to keep in the legal power range due to allen screw adjuster. I find the Spitfire to be a nice weight and balanced rifle to shoot especially with the carbine barrel.
Regards, Baz
