"Was expecting to have the same wiring harness as the picture...
besides that is a very solid gearbox, 390 fps with .25 on an 11.1 lipo (para m249 barrel length)

"great gearbox
only thing bad was fuse box was cracked in 2 places and my air nozle was cracked in half and the fuse was completely destroyed but didnt want to send it back cause its 3 parts to easily replace so i put the old air nozle on the new one and it was good to go
rate 5-5

"Came in the mail today and it works perfectly, i have an a&k M249 para and the gears were destroyed after years of wear and tear. This pre-upgraded gearbox shoots around 390 FPS and around 17 bps with a 9.6v 2300 mah battery.

Pros: shoots Hard
Fits snug in my gun
Upgraded piston
Great trigger response

Cons: my fuse housing was cracked(fixed easy with some electrical tape)
The wiring wasnt quite long enough to wire to the front so I cut the zip tie and it was plenty long
A little more expensive than the average m249 gearbox
Has that nasty green gearlubish stuff in the gears, cleaned that out right away

Overall, 5/5 for this upgraded box. Brought my m249 back from the grave, I would recommend this.
