Gun vent

[m0l0t0v]

I recently aired up my gun and it started venting really hard through the bolt. Any suggestions?

make sure all o-rings are in good condition and in place, should be a prob in the powertube, or overly worn bolt/sear

Turn your velocity down until it stops. If you can't get it back up to over 300fps without the venting, you have a bad piston reg spring assembly, or more likely, one that was tuned for a sub-lvl 10 bolt. $18 part from AGD.

That would be for venting out the rear, not the bolt. Bolt leaks are powertube related.

I'm going to buy the Xvalve Oring pack and change everything!

I opened it up and all the orings look grayish old..

try lubin each o-ring up, if those are the urethane o-rings, they might just need a lil oil.

Oh right. I read that wrong. Carry on.

Remove one side of the grips and try pushing the sear forward to manually reset before airing up. I don't know what causes it, but I had a couple that doing this fixed the problem.

Oil the o-rings, use the LARGEST LvL 10 carrier that DOES NOT leak, try holding the trigger does it still leak?

A parts kit is always a really good thing to have on hand anyway.
