Hey Guys:

I'm just installing a systema turbo motor and high speed gearbox on my M4. After setting the motor height (as instructed in the manual, where you run the gearbox after taking out the cylinder, piston, etc..) I put the mechbox in the gun and tried shooting it.

The first shot was good, but every shot after that was wierd. It did not sound crisp at all and I could also hear some grinding with every shot. I tried playing around with the motor adjustment screw and nothing would would (Iturned the screw all the way in until the motor would not turn, then I would loosen to try to set the correct motor height).

I then opened my gearbox again and there's no wear/tear on anything (gears, motor) except for the RED SYSTEMA PISTON which has a lotta wear to it. Like the first 3-4 teeth on the piston are quite worn down (like I have another AEG with >60,000 rounds through it and that piston doesn't even look like the one in this new gearbox).

Any ideas on what's preventing this gearbox from working properly?

Thanks in advance!
