I'm making my own airsoft gun and I need a pressure regulator for my HPA tank. It outputs 800 PSI which I need to bring down to about 130 PSI. Problem is, air pressure regulators that support 800 PSI cost around $120. I don't have the money for this, so I'm wondering if it'd be possible to use a ball valve that's almost completely closed to reduce the pressure. I found one that supports up to 1000 PSI on Amazon for around $7. via /r/DIY https://ift.tt/338kY5Q
