Review:
A good gearbox on par with the KWA M4 gearbox. One advantage of this gearbox over the KWA is that all 6 bearings are standard size 8mm bearings you can buy. Making it much easier to work on. The monster gear set can power up to M170 spring combined with magnum motor. The inner wall of the gearbox is reinforced, just like the Systema new type Mecha box shell, with all the inner walls thickened. Easy installation for most major brands of M4 / M16 series AEG. Great performance.
To install this gearbox on a MOD5 series, although it is a version 2, the nozzle, selector plate and trigger are not the same. Slight work and gearbox knowledge will be required.

"This gearbox works great until the single shot safety lock breaks off. This has happened in 2 of the same gearboxes. I would recommend a G&P over this gearbox all day long.

"Very nice gearbox. I got it to drop into my old Dboys and it's done it's job beautifully.

Pros- good fps, rather quiet, fits well, solidly built, and durable.

Cons- Semi-auto function is a little screwy, I have burst fire and full auto now. Wiring is extremely short.

I would absolutely recommend this and a bag of .25s to maximize the range of it.

"I bought this gearbox just under two years ago and it has served me well up to this point. I'll start with the good things about it. All of the internals are very strong and well made, however I have had to replace the spur gear due to a tooth fracturing off of it. While the internals are very good that doesn't matter at all if the gearbox shell isn't built well, which it is not. One week ago the front end of both halves of the shell fractured right off where this piston hits the cylinder head. This is a horrible gearbox in terms of longevity but when it works it works well, This gearbox has been run completely stock except for a change of gears due to the tooth fracture, I put in JG standard gears as a replacement. I do not go airsofting every weekend so this gearbox did not see extensive use, I usually go every 6 weeks or so. This break will render your gun useless and will cause stress on the hop up if you do not find the fracture in time. This may also cause your hop up to break leading to many headaches as I have experienced.

Would I recommend this? NO-NOT EVER, Unless you plan on only going airsofting once. I am being dead serious-DO NOT BUY THIS.
