Well you will definitely need a reg coming right off the scuba tank, otherwise it will be sending 2000-3000 PSI though your tubing, and that will probably blow most PVC. It would probably just be easier to use the scuba tank to fill other HPA bottles since they have the right fittings and regs already on them. I dont know much about setups like this, but you will need to regulate the air down before it sends through piping.
Why do people do this wanna-be hk thing? I mean hk people dont even play paintball, they just whine and start drama while wearing the weirdest stuff. Its amazing anyone embraces it.
Im putting the Hero back in Heroin.
I want your G6r parts and upgrades, sell them to me, because you wont get anything for them if you sell/trade them with the gun.
