Hey,

I am in need of some help in diagnosing my gun problems. I have little experience with AEGs or upgrades. Any help is greatly appreciated!


Here is the background:

-ICS M4A1-
Purchased used with upgraded spring(170%), systema bushings, high torque gears, upgraded wire installed by previous owner.

Fielded it for about 20mins before the piston had the first couple teeth break off.

Bought the ICS ma-56 upgrade kit for the upper gearbox half. Installed it but used a Systema m120 spring instead of the ICS upgraded spring included in the kit. Fired it and only fired in auto, regardless if semi or auto was selected. The gun seemed to misfire on a few shots and I even had a few bb's roll out the barrel. It also seemed to lack power. I continued firing it to try to figure out the full auto problem and then heard the gear box spin and heard gear ginding. I opened up the gun and found the teeth were being ground off the piston. I'm quite frusterated with the problems and the money I keep spending on this gun that I have yet to play with in a game.

Any suggestions or ideas I would greatly apprecaite as I plan to sell this gun once it is fixed and I don't want to pass on any problems to the next owner of this gun.

Thanks in advance,
Joel
