"Me building this gearbox to 33 RPS time lapse on my Airsoft Tech Channel!
https://youtu.be/pZRzPaGezqg?si=EOQjUGy8Xfq9Ei1U

Great gearbox, the shell held up well. The shimming was a bit loose defiently the sector gear having a horrible amount of play. As for the wiring ypu get a nice loq resistance wiring as well a full metal piston of pretty decent quality.

The compression was perfect, no leaks what so wver besides the air nozzle bleeding a bit of air.

8mm bearings are decent quality, not J caged but holds up well!

Ball bearinf spring guide
And its quick change which makes life easier!


As for compatibility, fits nicely in a specna arms vpdy and cyma body no problems!

Perun v2 hybrid mosfet fit perfectly, and I used shs 12:1 gears, shs piston, and a M100 spring.

"rec last 3 weeks and the reverse gear latch spring broke, didn't think it was worth sending back so I just asked if CS could send me the spring, they went one better, Keep the gearbox, we'll send you another. EXCELLENT! thank you EVIKE.

"This is a great gearbox at a very affordable price. I found my old Echo1 M4 from the mid 2000's while cleaning and wanted to get it working again since the gearbox was quite worn out. While it did take just a bit of coaxing to get everything to line up, it was very manageable and has worked great since. The 9mm bearings are worlds apart in performance than the old 6mm bushings. As for speed and fps, I don't have access to a chrono but I paired it with an Evike Monster Torque motor and even with a stock brass barrel, it shoots laser beams. It's well built and has great trigger response. For anyone looking for a replacement or a box to further upgrade I really recommend this unit.

"Ok so First I gotta say this think is perfect for my m4 AEG this gearbox completely renewed the life of the gun.

Pros:
Durable
very powerfull
easy to hook up
comes package in a foam container

Cons:
A little heavy but im one of those people who like heavy guns so it doesn't bother me.
Took a week to get to my house but i live in ga so that understandable


This gear box is all around amazing this has to be the best 60 bucks i ever spent.

I definently recommend this gear box for anybody who need a new durable fast gearbox for their AEG.

"this is a great gearbox I have no complaints except it did not come with the battery connector and the nozzle and spring guide where not white as in the picture but it is a great gearbox overall

"Solidly in the middle of the road gearbox

Pros:

Price-50 bucks for a complete gearbox ain't bad
7-mm bushings
Quick change spring-a nice feature, for sure
Decent quality wiring

Cons:

Sort of crappy internals.
Cheap 1-steel tooth piston that felt like garbage
cheap sleeved gears
so-so shim job
disconnector was wobbly.

Not a bad buy, but I would definitely upgrade some of the internals for a quality build.
