Product Information:
I bought this for My D-Boys PDW after it started acting up. The Shipping took 8 days with ground shipping. It was a little tight in my gun but it does not affect how it performance at all. just tricky to get the selector plate right. It was easy for me and i'm a big boy with meaty hands. Mine didn't come with a selector plate but I didn't think much of it since it didn't say it did. luckily my old one fit perfectly and after losing and finding the bead that goes under the selector switch a couple times I got it in there and now I run it with a high torque motor and a 7.4 LiPo. I have yet to see any thing bad from it except if i pull the trigger too far i hear a click and it wont fire until pull it again. Couple wraps of electrical tape and i'm good.

Pros:
Doesn't show signs of wear with a LiPo and high torque motor
Easy to install
Shoots straight
It hurts even at 30 yards


Cons:
Selector plate didn't come with it
a little tight in my PDW
can't pull the trigger super hard

Product Information:
I purchased this Gearbox to go in an A&K Masada. The stock gearbox was causing me nothing but problems and I was never able to get it working despite putting a lot of time and effort into it.

The only change that I needed to make to the JG gearbox was to change the air nozzle to a Masada length nozzle. The internals of the gearbox are of decent quality and much easier to work with than the stock A&K box. The gearbox is already shimmed pretty darn well so unless you need to replace a nozzle or downgrade the spring, there's no reason to even open it up.

Performance-wise, I noticed an immediate difference. The sound of the gearbox operation was much smoother and quieter than the stock gearbox. When previously the old gearbox would lock up frequently, the JG gearbox was consistent and the rate of fire improved because the motor wasn't working as hard to pull the gears. The spring in this box is either an M120 or M130 (I know the description says M130 but that could just be referring to what the gearbox can handle) so the FPS is probably 400+ depending on the AEG it's used in).

All in all, this is a great gearbox that is easy to install and in most cases won't require you to open the gearbox to start using it. This gearbox may be lacking a few features of higher end gearboxes (like the 8mm Ball Bearings on the G&P gearbox), but it is almost half the price and performs just fine.

Pros:
-Easy to Install
-Comes with M120 or M130 (no need to upgrade spring)
-Wiring is compatible with the stock wiring in most guns
-Fairly easy to work on internals

Cons:
-6mm Bushings (no ball bearings)
-Spring may make your gun too hot (400+ FPS) depending on your field rules (not really a con, but worth noting)

Product Information:
Ok yes it performs better than most low quality gearboxes but that's how it is with JG and most other low quality companies. they tune their gearboxes to perform like G&G and KWA but they use cheap parts that break. this gearbox only had about 3000 rounds when the piston stripped and the gun started to sound like someone poured sand in the gearbox. My brothers have owned 3 different JG guns and all of them had lots of problems. Our JG s-system had major feeding issues and wire issues and we ended up trading it for a new JG m16. this gun (not even kidding) almost started on fire. it stopped shooting, and when we opened up the stock to check the fuse smoke was pouring out! after that was fixed the gearbox shell cracked and it was scrapped and sold in parts. now our JG m4 had this gearbox. besides this gearbox breaking with very minimal use it also had hopup issues. Just dont waste your time with anything that is JG. Get a G4 its cheaper and it has G&Gs wonderful internals (but i think the G4 gearboxes dont have bearings though). anyway, this gearbox is simply crap.

Pros:
390 fps
18rps with a 9.6v battery
its a great way to waste your time and money
sets a good example as to why nobody should use JG guns


Cons:
broke after only 3000 shots

dont buy it.

Product Information:
Comes in all new armalite series enhanced/advanced JG guns.
In the stock gun, the full potential cannot be reached unless a metal one piece hop (requires a metal body) and a TBB is installed.
I recommend downgrading to m110-m120 for a m4, you don't need mondo fps in a carbine.
Fine for m16 though a m120 isn't a bad idea if you have strict fps limits.
LIPOLY READY!!!!! It handles a LiPo better than many $300 gearboxes, the gears are great steel gears, $27, but said to pull up to m160 (no way that would work) With the JG high torque m120 motor this gearbox can take a 9.6v 2000 mah battery and run 18 rps with it.

5/5 for price
5/5 for performance
4/5 for need to lower spring rate in many cases

Pros:
-durable
-high fps (may be a con) I get 440+ fps in my m16 with an upgraded hop and TBB
-metal bushings
-comes in stock new JG guns
-cheap beyond belief, you could just get this to use as parts if you desire

Cons:
-high fps, the front wire should be m110 or m120, since carbines and cqb need low fps
-bushings are 6mm (though they look smaller) so they can't handle a big load
-don't get if you have no clue how to take your gun apart
-expect the need to tune or repair in the long run, it is good, but not perfect
-spring has lots of coils and is really loud for some reason...
-you might want to lube this if you are good with gearboxes, just for better performance
