Right....I believe they come with an ASA on teh bottom of the grip, from teh factory...all you need to do is either:
A) Buy a Preset LOW PRESSURE air system, from Planet or Fat Bobs etc, with an out put of 450 PSI, and screw it into the ASA.
B)Buy an ADJUSTABLE air system, and set the output to whatevr it needs to be for the Angel, which I think is around 450psi. Bolt that to the grip frame, and plumb it in...or if its a Nitro Duck Extreme reg, screw it into the ASA...as it looks like a preset (nice and compact) but is actually adjustable, and really consistent.
If you ant your own air supply, you will need a dive tank and fill rig...if not, use teh air at Tourneys or at your local site...does your local site run air?
