I had listed these parts because of recent failures in our guns:
- Hop-up Bucking - My friend's new King Arm M4 lost fps (dropped to 100 fps) after only shooting about 300 BBs. Fixed by replacing with a Guarder clear hop-up bucking that I had on hand.
- Piston - I shredded the teeth on an Aftermath M4 - which I had upgraded with a M120 spring (yes, I know I was asking for it!)
- Piston head - Aftermath M4 had poor compression
- Nozzle
- Cylinder head - Poor seal - again this was on an Aftermath that I was trying to upgrade
- Spring Guide -Stripped the back nut on a metal spring guide, bearing spring guide broke apart
- Little clips to connect the wires to the motor (I've had them snap apart)
Now that I think about it, it seems that most of the failures were related to me playing around with the Aftermath (just a learning experience).
So, maybe the hop-up bucking (rubber?) is all that I need, and a piston. I can always strip other parts out of the Aftermath for a temporary fix.
