"who ever made this needs a lesson on how gearboxes work,
THEY PUT BALL BEARINGS IN THE GEARBOX!!!!!!!!!!!
for all you techs out there you know
this means this gearbox will fail very fast

pros;
VERYY strong gearbox shell
good compression
strong gears

cons:
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

"incredible gearbox
well I can start off by saying I was very concerned about getting this gearbox mainly because such a heavy spring can do a lot of damage to your gearbox I bought the M 130 about a year and a half ago and it was really good but after all that's just an M 130 but I am insanely impressed with this one it is built so well it's incredibly solid mine was shimmed perfectly and it has an incredible air seal when I first started shooting it it didn't seem that powerful but 30 rounds later I'm blowing through a glass bottle at 40 feet away with a .43 mad bull

just a few things for people to know about this gearbox

people complain because the back wiring is short well with such a heavy spring and having to use a heavy battery you should buy rear wiring that has a fuse

this can use the aim monster torque motor or the Evike monster motor just know the rate of fire isn't going to be all that

with that being said to all the people complaining about the low rate of fire I don't know why you would want to use that on someone because honestly that just makes you the part of the human body that releases fecal matter

it may be somewhat large for some bodies but when you have those kind of parts in your gearbox you're going to be thankful it has that big bulky shell

all in all I give it 10 out of 5 stars matrix outdid themselves once again just keep in mind hardly any field will let this type of gearbox play unless your gun is semi only

"ive had this gearbox for about 3 months now.it has held up perfect. i didn't open this up at all. i honestly just "dropped it in" my gun. the gearbox was put into my m16 along with many other upgrades. after complete installation the fps i got was 560~580 and a ROF of 16rps on full auto (11.1v 20c 1600MaH). the gearbox had about 8000 rounds through it so far and yet nothing broke. the matrix m160 gearbox is a great upgrade for any v2 gun. now this gearbox wont work without the following.

HI-torgue motor
11.1_
or 9.6(not recommended)
mosfet (MUST HAVE!!!)

with my 6.02 tbb and Rhop i get 300+ ft. effective range!!!
P.s. if your buying the matrix magnum motor for this it works great.... except the pinion gear is horrible! i strongly suggest u get another pinion gear because mine lasted about 500 shots i replaced it and its been fine ever since :)

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.
