Prometheus EG Hard Gearbox Shell V2 (6mm)
The 6mm gearbox shell is a critically acclaimed upgrade part that reinforced the shell and allows for ideal teching of an AEG gearbox. 
Robust Metal 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.
