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.
