blackdraft phoenix m power 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 and affordable HPA engine with excellent performance in SMG configurations).
• M-POWER chamber (hop-up chamber optimized for HPA with precise bucking adjustment).

This kit ensures perfect centering of the Phoenix nozzle with the M-POWER chamber within the compact ICS MPX/CXP platform. Fully compatible with the original ICS lower receiver, maintaining the structural rigidity of the ICS split gearbox system.

Installation and adjustment

1. Printing and preparation

• Print the parts with 65–80% infill.
• Lightly sand internal areas to ensure a perfect fit in the compact MPX/CXP chassis.
• Apply dry lubricant to contact surfaces if needed.

2. Installation in the ICS replica

• Insert the base into the original ICS lower receiver and install the M3 inserts.
• Mount the rear clip using the ICS folding stock mounting point.
• Install the M-POWER chamber with the inner barrel; the top cap locks the assembly and keeps everything centered.
• Route the Phoenix HPA tube through the side clip designed for the limited space inside the MPX/CXP body.

3. Final fixation

• Secure the rear plate using an M5 screw with washer for maximum rigidity.
• Verify that the Phoenix nozzle enters the M-POWER chamber centered, without lateral play.
• Perform dry feeding tests and adjust the Phoenix pressure according to your SMG configuration.
