It cost me $40 for labor and a new KWA piston head. I guess we will know after I get to play several games and see what happened. As for o-rings being old, the gun was not even 2 months old when it started happening. I would've Sen it to KWA for repair, but I sent my am9 ptp to them and as soon as I shot it, the breach rails snapped. I've got 3 techs were I live that live there life off of that business and after God knows how many years of airsoft gb work, I trust them.
You got a brand new KWA piston head for a gun that was only two months old?
What was wrong with the original stock piston head?
I own 4 KWA guns and have never had a problem with the piston head.
As far as the O-ring, maybe it was bad, maybe not.
When you chrono'd your gun before repair, did you have your Hop-up turned all the way on?
What weight bb's were you using?
Did you clean out the inner barrel and Hop-up unit / bucking before using?
Did you do any inner barrel or bucking swaps before you chrono'd?
What brand chrono was it?

As for a shattered air nozzle, well now that I have a better word for it, it wasn't actually shattered, it got stuck when it was going back and I guess something was put of line, but a piece the shape of an " n" was knocked partly out. How that happens, I don't know, but it does.
This is the kind of thing that can happen from time to time when someone opens up the gearbox and works on it. I have never heard of a KWA air nozzle becoming unseated in stock form, especially being only two months old.
I think there is more to this story than being disclosed.
Did you buy the gun brand new or used?
Where / who did you buy this gun from?
you are speaking with those who own or have owned multiple KWA guns and most of us tech our own guns. We know the stengths and tolerance levels of these guns first hand.
