[bdflipster]

Hey! I just got a pi-E2 black dragun and i just ordered a preset HPA tank at 850psi. I was wondering if i could turn my gun into Low Pressure but still use the high pressure preset tank. PLZ help i wanna get this gun going.

All you need is good low pressure Inline Regulator like the Bob Long Torpedo and the required LP parts such as: high flow bolt, high flow valve, high flow VA, different Valve and Striker springs.

If I may ask, why do you want to go LP?
