"I bought this awhile back for my g36c and finally got it into my g36c and ready to test fire it because I was so excited to finally shoot this gun that i bought from a friend but the gearbox broke so i bought this and i was excited when it arrived but when it was in my gun the air nozzle wouldn't move so i attempted to open up the gearbox to try to fix it and the a part of the trigger mechanism broke so even if I fixed the gearbox, I would then have to flick the trigger forward after everytime I pulled the trigger

"The gearbox is probably good, but the motor was locked up when I received it. The GB seemed to be used and I got the gearbox locked up right out of the box. The spring and piston was locked back and I had to pull the anti reversal latch. Wasn't very impressed as this wasn't advertised as used or refurbished.

"I bought this gearbox for a JG G36K. My friends broke on him, his trigger contacts were broken at the wire and I figured I'd just set him up with a new one because his was many years old. I got the gearbox today and to my dismay, the gearbox was locked up, and the spring and piston was locked back and not returned to resting position. The gearbox was used and I was disappointed to also find out the motor wasn't working at all. I then tried my friends old motor in its place with the wires that came with the new gearbox and my old motor spun perfectly. So I reccomend not buying this unless you want to have some work to do to it. After replacing the old motor I installed it and it seems to work fine. Though I have no high hopes for it.
