Polarstar F2 Maxx ME alignment ring

This is a custom alignment ring for the airsoft Polarstar F2 engine and the Maxx ME hop up chamber for M4 platform. For me it worked wonders, accuracy and consistency is perfect now.

Some modifications needed:
-gearbox need to be cut in half as shown in the picture
-an AEG spring has to be cut to the desired length to place between the end piece and the receiver
3x M3 screws and nuts are needed to assemble.

It may work with other Maxx chambers but I have not tested them yet.
You should measure the inner diameter of your upper receiver and modify the end piece accordingly. The base dimensions should work for Cyma receivers.
.STP files included in case you want to modify them.
