"For m249 replacement gearbox

Pros:

1. It has the heavy duty micro switch.

2. Probably the most user friendly gearbox out there.

Cons:

1. Nozzle was broken due to improper packaging.

2. Shim job on the gears was so tight that each shim was slightly concaved/warped.

3. Spur gear was warped.


This gearbox is easy to work on. After polishing the interior, swapping new spur gear with the old one and properly shimming, greasing and oiling...the gearbox and gun in general work great...just required some tlc.

"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.
