So I think this is a great little gun for what it is.. but it need work like any other aea gun... it's ok for 3 good shots at the 3600psi when it works right... they made the pop-it for the valve out of steel so without the right amount of preload on the pop-it it has a bad habit of bouncing and dumping a lot of air and sounds like a Simi auto.. so now we taking this gun apart and see what we can do..
