Hi , i was planning to make airsoft full auto gun , with qev and adjustable pop off valve. The problem is when i fill the gun with air pop off dont pilot qev and all air goes thru pop off valve and it sounds like ss-shhhhhh. I think pop off cant pilot qev beacuse the air is still going from blowgun....

How can i done that properly? I want pressure something about 200 psi or 300.

Hi guys I have a question. Can I fill a 0,6 liters fire extinguisher tank with dry ice? Will this produce co2 pressure? Do I need water? How much pressure can it do?

How about dry ice and water, can I just use 0,6 liters fire extinguisher fill it with water and add some dry ice, how much pressure of co2 will it be able to produce?

I can only pump 7 bar of air pressure, I was thinking about acetylene because he have high pressure

Hello, I was thinking about acetylene as the propellant for qev airgun. Will it be safe to shoot with this? I have some carbide so I can produce acetylene from these.
