SUPER URGENT HELP PLOX

Okay, it seems the AS gods are against me enjoying myself at my next OP, which is this SATURDAY. Everything that can go wrong, now officially has.

I was just nearly wetting my pants because of how beautifully my KWA M4 was TEARING apart a paper plate at 80 yards away, almost perfect accuracy, 380 FPS at 1200 RPM. Then, on the drop of a dime, it broke in my hands.

Well, not neccesarily, here's what's happening:
Gun still shoots perfectly fine, accuracy, ROF, power, but with every BB that is shot, a rather loud "cracking" sound can be heard from somewhere in the GB. Please help me. I have several ideas but I'm hoping someone here has a better one, or possibly a miracle fix, which I will trade for ten smileys similar to this one:

But until then, I'll be

How old is the gun? KWA has a 60 day (?) or 30 day (?) warranty on their guns.

Cylinder or Piston issue? Maybe your Cylinder head is hitting something.

I'm almost certain it's a Piston issue, but the cylinder is a possibility.

Upon close inspectionn, I've concluded two things.....

1. this gun is far past its warrenty!!!!
2.Bevel gear, Motor Height, and all Hop-Up parts are in place/correct. the cracking is almost certainly coming from the Piston, whi I don't mind replacing with a real nice one.

With all the upgrades I've been putting in this guy, I figured it was a matter of time before something broke....but how inconvenient of a time!!!
I think I'm just going to do a whole GB overhaul...re-do all the internals to my liking

Maybe your piston head is hitting something inside the cylinder... Hmm. This is a tough one.

It sounds as if it's coming from the rear though...towards the back of the GB

Thats what she said???

Did you try tightening the little screw thingy? (Shuudddup I know what Im talking bout )

Which, the one that adjusts Motor Height??
Yep, nothing changed.

PS I LOL'd

Um, maybe your spring is catching on the spring guide and making a funny noise?

I'll buy it from you if you don't want to fix it.

Hahaaa, you'd if you saw the price tag on this puppy, I've put so much into it...naw, I'm going to take it up to my shop and have them check it out (under my supervision) and fix 'er up.

...Unless you REALLY wanted her, we could talk maybe. I wouldn't let her go easy though.

There is no telling until you can get the mechbox open. But it is too late for that now.

I can only say it Looks like this gun has a stripped piston, and possibly stripped at the piston if you've been running a battery you weren't supposed to use.
