Well i just got my new FCC g2 motor in today with the steel pinion gear and shot it a few times, it was amazing ! the sound is incredible, however the steel pinion gear stripped the bevel gear so i was planning on just replacing with it with the systema but i cannot find them in stock anywhere ! also the grip would not fit over the motor because it is slightly bigger so i will need to buy a different pistol grip too.
