"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.

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

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.
