The Benjamin Disco pump will work on the Condor,,, you can order the fill adapter at Pyramydair and it will affix to the pump hose. I've been told that the Air Forced pump and the Disco pump are actually pretty much the same pump and made by the same manufacturer. I can't confirm that but if you look at the 2 of em side by side they do appear identical.
Perhaps another GTA member who knows for sure could confirm or refute that....
But in any event,,, the disco pump can be used on the condor (but that first fill from empty is gonna wear you out... After the first fill it won't be so bad cause you'll only be topping off the Air Force tank. I have a scuba tank setup for my Condor and my Talon , but I do use my Air Force pump to to top off the tanks after a days hunting and it's not bad at all......
