Light hiss down barrel
 
Ok, gun is a stock lvl7 . I have a very light hiss down the barrel. I've replaced three power tube o rings and even tried a different spacer, and its still there. Would it be something in the on/off?

Which size spacer did you use? Bigger or smaller?

If you pull and hold the trigger down, that will depressurize the power tube o-rings. If the leaking stops, then you know the issue is within the powertube.

Another test would be to stick a dowel down the breech and move the bolt around to see if the leaking changes.

And if the leak doesn't stop, then start checking all the o-rings in your on/off assembly. If all else fails, take it all down, clean, and put back together. Sometimes little bits of debris or ptfe tape can cause those kinds of leaks too.

I tried pulling the trigger and it stops, also no water sprinkler. The original spacer as a agd2.2. I used a proteam purple spacer to try. No change. Ill try a full strip down, but I just have done a full rebuild on it.

If it stops trigger down it's in the power tube, check that the o-rings are clean.

Can you measure those spacers? They may be the same length. I've never seen an AGD spacer with a single digit on it.

Ill check

Justus 03-30-2013 07:11 PM

Yeah, they're usually .210, .215, .220, .225, .230. In a pinch, you can throw a ULT shim on there to bring it up .005, if you don't have a larger spacer.

I might had got the number on the ring wrong. Ill double check it when I can,. It will be a while before I can mess with as I have to spend the next six weeks in training in Columbia. This sucks :(
