The Prometheus 8mm gearbox shell is a critically acclaimed upgrade part that reinforced the shell and allows for ideal teching of an AEG gearbox. Robust materials and easily identifiable part positions are printed to the outer casing of the shell which allows the user to quickly see what is compatible and needed to optimize the internals of your AEG. Each section of the shell itself is removable and workable independent of the others which makes working on the product much easier. Finally, routing channels and smartly placed machined cuts allow for better wire management.

Tech's Dream

I am a tech for my team and when i watched the unboxing / review of the 6mm version on Airsoftology i totally agreed with him and wish Prometheus would make a 8mm version. When I saw this, I got my whole team to get them and I have to say these are a tech's dream. The fit and finish are top notch and the best part is I don't have to stress about wiring when they cut in channels for better management. If you are a tech or want to get into it, this is by far the best option you can get your hands on as of right now!
