reducing ’ping’ noise

Put some shrink wrap on your sear spring. Thats hould help some.

tubing, it's used for electrical connections. find it at any hdwr store

I wonder if putting some more Orings as an extra buffer for the bolt would do anything.

Or what about some rubber grommets on the asa bolts to give some extra vibration dampening?

Just throwing some stuff out there.

Oh, and I placed a silicone 'foot' that you would use under your computer monitor, or under furniture to keep it from scratching, on the front of the rear bolt to deaden the impact sound from hitting the valve, so that might be construed as more o-rings.

Has anyone else had this problem?  It seems kind of strange.

I should mention that I have done these things in order to try and get rid of the ping, so none of them are what is causing it.

Actually, unfortunately it's loud enough to be heard from a ways away. :( But I will try putting the heat shrink tubing over it tomorrow and see how it goes.  Thanks!  It's just frustrating that it is so loud. 

its not the spring making the noise its the co2 tank... i had the same problem but fixed it...



just run HPA

I have a stupid question. I got the heat shrink, but how do you put it on?  Just a small piece over the unextended spring, or extend the spring to about the size it will be as it sits in the marker, and then put a piece of heat shrink over that the spring when it is extended?

Thanks!

Another stupid question (thank you for bearing with me), but the spring itself is only about half and inch long.  So, because I am horrible about picturing things in my mind, do I cut it down to the size of the actual unextended spring, and then heat it onto the spring?

Edit:  Ok, I believe that I answered my own question not long after I asked it.  I took my receivers apart and was just messing around with the different internals, putting them threw the same motions that they would go through during actual firing.  I found that when the sear went back into place as the bolt was cocked, it made a 'click' noise as it was held in place by the rear bolt 'catch', for lack of a better word.  This click noise was accompanied by a 'ping' in the sear spring, as has been mentioned before as the problem for the ping noise during firing.

I decided to try different ways of applying the heat shrink tubing.  I first just put it on the spring with the spring compressed and in an idle state, with just enough tubing to cover the spring, and heated it on.   I then repeated the test of manually moving the bolt back and listened for the pinging noise from the spring.  It was still there, although I noticed that if I placed the slightest pressure on the spring with my fingertip, it went away.  So I removed the tubing, and measured it out to go on while the spring was in position in the marker, which meant a larger piece of tubing to cover the extended spring. 

From there I placed the spring with tubing in place, and carefully turning my marker over, I heated the tubing to shrink it.  Then I repeated the manual firing test, and there was no ping noise to be heard when I cocked the bolt.  So in effect, any noise from the sear spring, is now gone and dampened down to minimal (I couldn't hear it at all).  I haven't been able to test the marker out gassed up as it's midnight, but as soon as I do, I will leave a report here of how it sounded in the morning.  I am leaving all of this info in case someone else wants to figure out how to do it, and can find it by searching. 

Thanks again for your help folks, it's much appreciated.

It IS the spring. But a co2 tank will reverberate more, and make the ping louder.

I still think some grommets on the asa bolts or a rubber gasket between the asa and grip, will take alot more ping out of the marker.
