"I replaced my existing gear box that has a m120 spring with this one and all was fine at first.
I donít have a chrono but I can tell the BBs fly a lot faster.
The motor that came with M4 S-System was adequate(using 10.8 v batt) to work the new 160 spring.

But in less than 50 rounds the new gear box locked up... I was really bummed out.

What I found is that the piston head screw had come loose causing the spring bearings and baring alignment nut to get jammed up in the cylinder locking up everything.
So much for QA.

Anyway, I re-assembled the piston/bearing and used red lock tight on the screw to make sure this didnít happen again.
Got the gear box back together and into my M4 and so far itís been working fine.
Eventually I'll need a stronger motor as the rate of fire in auto is relatively slow.

As a result of the total jam up caused by a loose piston head screw, I can only give it 3 starts as it was a lot of work to fix it.
The gear box is really good, donít get me wrongÖ, its feels solid and appears to have excellent parts, but a loose screw?

"I just got this gearbox and it appears to be great. I had it checked out by a certified airsoft technician to ensure it was properly shimmed. To my surprise it was in perfect shimming condition so that was awesome. Unfortunately the piston broke as soon as we tested it. Upon further investigation the spur gear lost one or two teeth. Not sure why this happened even though I used the recommended Matrix Magnum motor with it. I am waiting on Evike to respond to exchange the unit or the broken parts. This appears to be a solid gearbox. Even though I had a misfortune of events, I believe this to be an awesome piece of gear. Not to mention that Evike stands behind all their products and have a great customer support base. The grease is very minimal so if you are opening this gearbox then you will need to add some grease. Please be advised that I was fortunate in getting a properly shimmed gearbox. You still need to have it checked prior to using as stated in the product description. I also highly recommend you use a certified airsoft technician to do this work unless you are very familiar with gearboxes. I hope this review helps out. Have fun!

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.
