"I already did 1 review and if your still not convinced watch my video review

I'm using this as a DMR gearbox anyone expecting to use this on full auto should not expect to have this gear box for very long it is a very powerful spring you're asking for a lot if you try to run it on full auto

if you want to build a powerful gun I highly recommend this gear box for a drop in gearbox you can't go bad with this one I've been using mine for about 3 months now and I have absolutely zero problems with mine

"I used a 650mm tightbore barrel and the Matrix Godzilla motor, with .2 bbs I got 520fps. ROF is quite low (as expected). After firing about 20 shots it stopped working because the motor shredded the wiring in the gearbox. The wiring in this gearbox is wayyyy too close to the gears. Not a very good gearbox, not pleased with this product.

"who ever made this needs a lesson on how gearboxes work,
for all you techs out there you know
this means this gearbox will fail very fast

VERYY strong gearbox shell
good compression
strong gears

no mosfet
bad piston head
teribble contacts
ball bearings
piston stripped
only 480-520 fps depending on your barrel length
(discription says 500-600 fps)
not a great upgrade

matrix internals are like a hit or loose, sometimes there amazing (like this gearbox shell) sometimes they suck....

jut ask a tech to build one for you who has experience and knows how to build high fps setups

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.
