if my chamber will be iron pipe and i'll have a blowgun connect to the chamber, it will be fine no?


I have never used iron pipe before so I do not know how it will hold up. Theoretically it should be fine though. If you do not have a regulator to reduce the pressure from 800psi to around 100psi, DO NOT USE A BLOWGUN. It is not designed for that kind of pressure. You will need a metal ball valve for firing and one for filling the chamber (chamber valve for increased efficiency and less waste (you don't have to have one but I recommend them)).

If you don't have a way to regulate the pressure down to around 100psi, the 800psi will a be like holding a live grenade in your hand. The sprinkler valve is the grenade. Not a good idea. If you are going to use unregulated Co2 or HPA, you will need all metal valves, fittings, pipe, and adapters. PVC only to be used for barrel assembly and low pressure.
