Aluminium Hop-Up Chamber CNC Maxx Model M4Ei (For ICS M4)

Aluminum CNC Hop-Up chamber

The highest quality Hop-Up chamber designed for the tuning of ICS replicas based on the AR platform.

*The Enchanced version of the chamber features an improved pressure system, thanks to an additional O-ring added to the pressure frame of the spacer.  Another important change is the addition of shims to the adapter, so that the pressure of the chamber to the face of the gearbox can be adjusted and the nozzle length thus adjusted

Rotational chambers of the brand Maxx Model Products are dedicated to the most demanding players, offering unprecedented precision performance and perfect operation of the HU system in the replica.

Chamber features:

- precisely manufactured from a block of Aerospace Aluminium using CNC technology
