blackdraft phoenix gate eon alignment kit v2 1 ics mpx

Version 2.1 of the hop-up alignment system, designed specifically for ICS MPX/CXP HPA replicas using:

• Blackdraft Phoenix engine (compact high-performance HPA engine with simple configuration).
• GATE EON chamber (hop-up chamber designed for HPA platforms with precise adjustment and excellent feeding control).

This kit guarantees perfect alignment between the Phoenix nozzle and the GATE EON chamber, eliminating offset issues that can affect consistency in compact platforms such as ICS MPX/CXP. Fully compatible with the original ICS lower receiver.

Installation and adjustment

1. Printing and preparation

• Print the parts with 65–80% infill.

2. Installation in the replica

• Insert the base into the original ICS lower receiver (compatible without modifications).
• Mount the rear clip aligned with the ICS rear body pin.
• Install the GATE EON chamber with the inner barrel; the top cap locks the assembly while keeping everything centered.
• Route the Blackdraft Phoenix HPA line through the side clip, optimized for the compact MPX/CXP layout.

3. Final fixation

• Secure the rear plate using an M5 screw with washer for maximum rigidity.
