Rock Bottom Airsoft talks about the various components that make at an airsoft AEG gearbox plus upgrade options... "In this video we are going to take a look at the internals of our AEG mechboxes in airsoft. We will look at the parts we may want to upgrade, costs and what they are.

I won't be looking in depth at these parts this time as that would relate to a specific build. this is just a basic understanding of what the parts are, do and whether they need an upgrade normally.

We will not be looking at the electrical components related to the gearbox this time. I will look to cover those in another video. This video is already pretty lengthy without going into Mosfets, wire gauges and motors."
