I tried this set up and it just blew out of the air blower and didnt release or transfer air to the barrel. ..why how would you fix that?

You see muflers blowing apart from a backfire, so it's a guess what it would hold. I've just recently made a similar looking tank out if galvanized pipe...that sucker aint letting go too easy.

Just caught the bug for home made air soft guns and have progressed from modifying nerf guns to building qev guns. So I have successfully made a very simple single charge air soft cannon, where I have an air cylinder that I charge up with compressed air disconnect the line and go and damage some can...
