"Horrible gearbox. Mine didn't work right out of the box. I should have returned it, but I thought it would be a simple fix and I needed it ASAP. Come to find out it was a bad pour on the gearbox shell and it was rubbing on the gears. By opening it up I voided the warranty. I ended up buying a g&p gearbox and it worked great. I guess I will just use the parts inside the gearbox as spares. It just doesn't make sense to me to put good parts in a bad gearbox shell. The shell felt very light and flimsy compared to other gearbox shells I have. So I have no idea why it says it reinforced. I won't be buying anymore AIM/Matrix products in the future. Heck the G&P gearbox was even cheaper and it's much higher quality.

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.
