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.
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 :) "I've probably put about 300rds full auto and about 190rds on semi through my m4 with 509mm 6.01 barrel, and I have to say it feels like its just getting better the more rounds i put through it. Great gearbox so far. I need to chrono it still, but for reference, i've seen the bb travel atleast 200 ft(.20) before losing it, however the flight pattern was gnarley. At 50 ft It shot through cardboard into a wood door and shattered bbs to peices. The trigger response is surprisingly efficient, smooth, and instantaneous, however if your hopup/bucking is not the right type some trigger/operation issues will occur. The thing sounds like a monster and will easily let people know you are there, but does make an awesome sound I must say. The Matrix magnum motor did not mesh with the gears so I purchased an echo 1 that seems to have given me quite the RPS and overall power I was looking for using a 9.6v. Overall A great gearbox at a great price. Looks and feels great, has been reliable so far and feels like it will continue to do so. Read More Reviews Write a Review

Complete AEG Gearbox 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.
