I sprung a ....

[Widget23]

LEAK! It's an FX Royale 500 in 0.25 with the FX Regulator installed by AOA.

The symptom is there is a leak sound after the fun is fired, and lasts for maybe 20-40 seconds. It's very faint - it needs to be quiet in order to hear it.

AND ... it does not happen all the time.

The gun seems to shoot fine (accuracy-wise).

I'm trying to isolate where it is. I **THINK** I can hear the leak near where the barrel attaches - so in front of the block.

Suggestions? Ideas? Where to look and how to solve this would be great. I've never taken the gun apart to do anything to it.

Thanks!

Could be the plenum tube filling back up. My .25 Impact X does this but only for a few seconds.

Could be the regulator taking its sweat time doing its job.

My guess would also be the plenum refilling. You probably hear the "leak" sound more when your reg is falling off

I agree sounds to me like the reg refilling the plenum. Reg not working correctly if that's so and taking that long. Have you chronied it lately?

Above is probably right. But when in doubt, send to Ernest as he’s the best & most affordable for common problems.

Others have their specialties that they’re best at.

If it were a "leak" you'd be losing air. Are you? If it is an internal problem the gun would exhibit shooting problems.

I hear this in my impact, but it only lasts a couple of seconds. It is the plenum stabilizing. I understand we should give the gun 9 seconds or so to stabilize between shots for maximum regulator consistency.

Thanks for all the ideas!

No, not losing air that I can tell. Bottle pressure remains normal.

I've not chrono-ed it lately. That is a good idea.

I just refilled the bottle to max and will see how that affects the sound.
