i got this gearbox and i put it in a m16. with the stock hop up it was shooting 430 fps. when i upgraded the hop up to the mad bull ultimite hop up the fps went to 500 with .2s. i use a 11.1v battery and it has some missfeeding. the shim job is bad.

pros
lipo ready
500 Fps with the right hardware

cons
bad shim job
needs a mosfet for lipos.

I bought this Gearbox to go into my G&G CM16. Had no problems with the install at all except for the fact the the wiring to the back is so short. I had to snip the connectors and rewire the back wiring. So if it wasn't for that this GB would definitely be a great upgrade to any AEG. 4 stars for the wires being so short.

Well, this gearbox is awesome. I put it in an M16, without any other upgrades at all. I can't field it. FPS is 505. I thought this was going to get me ~460 fps.

I purchased this GB about 3 Months ago and installed it on a Frankenstein TSD/SRC M16a2 with a King Arms Hop-up, Matrix TBB, and 11.1v/4000mah lipo. My first mistake was to use a hard bucking (4-5 bb's would shoot/roll out at a time). Contrary to what many say on here, a soft bucking is best for this GB. The construction is very sturdy and it seems to handle my lipo well. I've used it in the field maybe 10 or so times and it performs well, although it shoots a little wild even with .25's. I'm installing a better quality bucking with a concave spacer in an attempt to fix this. I didn't know how powerful it was until I got it chrono'ed at an op last weekend: consistent 435 fps with .28's! The fps limit was 420, but luckily my friend was working the chrono booth and let it slide.

Pros:
-Great quality for the price
-Sturdy/well built
-Powerful

Cons:
-A little noisy
-May be too "hot" for some ops.
-Shoots a little wild (probably not the GB's fault though)

This thing is great! It's just as thick as KWA's gearboxes, and has great reliability and POWER. LOTS of power. Get it! You won't be sorry! It's without a doubt THE best gearbox I've had to date. Handles the M130 in stride, and is easy to upgrade (though I don't know why you ever would!)

5 stars, absolutely love it, zero cons whatsoever.

I would say this is a great deal. However it has no grease on the insides and the shim job is OK not the best or worst. The gun shoots WAY to hard. On my dboy scar it shoots through shirts, house siding, curtains. If you take it apart it will probably take 2 people to re assemble it. The back wire to the battery is extremely short. Overall this is great, id buy it again but i would get the m120 this one is shooting 500-600+ no one will play with you. i gave it a 4/5 because of the wire shortage
