This is my Phantom set up for Stock Class: Stock Class Body, Vertical ASA, 12 Gram Bucket Changer
This is the same gun with a different body set for HPA that I ran with in the Winter. Here I have a right feed body, CP rail and On/Off ASA (as Nahib_Stilgar said the tank is at a 5* angle so I put a #10 washer under 1 of the screws to offset the angle), 2 macro line fittings and a 13 CI tank.
Here I have it set up with an On/Off ASA going into a 1/8 adaptor into the Vertical ASA (I converted this in about 5 minutes).
I hope this helps a little bit
