The air flowing through a regulator flows through a tiny hole (about 1 mm).... so the only air that is available to produce the shot is that downstream of the regulator.... Ideally, you want about 1 cc of volume for every FPE you want the gun to produce.... and 1/2 cc per FPE is the practical minimum.... If the volume is smaller than that, the pressure drop during the shot cycle is too great, and you have to compensate by increasing the setpoint of the regulator.... and efficiency suffers.... A .50 cal would require a huge plenum, you may not find that practical with your basic layout....

I can see I will be PM'ing you in the future when guidance is required. Thanks so much for the insight. Everything you said passes the logic test.
Just a little update on the fifty... I have decided to wait until my PAL arrives in the mail before I add the trigger and install a working valve. I just want to play it safe. No need to cause any trouble for myself just to have a little fun!
Still on the look out for a 13ci HPA tank if anyone in the lower mainland has a line on one drop me a PM!
