My gun leaks air very bad.

[Space Cowboy]

I took my gun apart today to give it a real good cleaning. When I put it back together and screwed on the tank it started leaking air at a very fast rate. It was very loud and I lost 1000 psi in about 5 seconds. I think that I put it together wrong and the sear isn't catching the bolt. I have taken it apart many times before and never had this problem. Can anybody tell me what I did wrong or if something is broken?

lol...what did you clean it with ?

[ralicea]

Is it leaking from the front or back? Is it an RT valve or regular valve? Please provide more details?

Hold the trigger when you gas it up and see if it leaks. If not, you probably forgot to put the PT o-ring in, or it's in the wrong order. O-ring goes in first, then spacer, then PT tip.

Ok, first of all I didn't clean it with anything. I just wiped off the paint from my last ball chop and if you are just going to laugh you might as well not post. I can't tell where it is leaking from, I think it's downt the barrel. I checked the powertube already and everything is ok in there. I do pull the triger when I gas it up and that doesn't stop it. It is an RT valve.
