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 an excellent price-to-performance ratio).
  • PROWIN chamber (high-precision hop-up chamber optimized for compact submachine gun platforms).

BlackDraft Phoenix: This version is a pre-2026 beta release that is not compatible with 2026. If you need it, you can request it.

This kit ensures perfect alignment between the Phoenix nozzle and the PROWIN chamber, adapted to the compact geometry of ICS MPX/CXP platforms. Fully compatible with the original ICS lower receiver and ICS split gearbox systems.

This template was created for Phoenix Beta, which was released before 2026, so if you need the 2026 version, just let me know and I'll put it together for you.

What the kit includes

  • Rear clip optimized for the ICS MPX/CXP rear body pin or fixed stock.
  • Base with housing for M3 threaded inserts (optional brass for durability).
  • Compact side clip for routing the HPA tube/line.
  • Front locking top cap specifically designed for the PROWIN chamber.
  • Rear plate with mounting point for an M5 screw (structural reinforcement).

Installation and adjustment

1. Printing and preparation

  • Print the parts with 65–80% infill.
  • Lightly sand internal areas to ensure a perfect fit within the compact MPX/CXP receiver.
  • Apply dry lubricant on sliding surfaces to facilitate installation in tight geometries.

2. Installation in the replica

  • Insert the base directly into the original ICS lower receiver (no modifications required).
  • Mount the rear clip using the ICS OEM rear body pin.
  • Install the PROWIN chamber with the inner barrel; the top cap locks the assembly while adapting to the compact MPX/CXP geometry.
  • Route the Blackdraft Phoenix HPA line through the side clip designed for the limited internal space.

3. Final fixation

  • Secure the rear plate using an M5 screw with washer for maximum stability.
  • Verify that the Phoenix nozzle enters the PROWIN chamber perfectly centered without lateral play.
  • Perform feeding tests considering the compact internal layout of ICS MPX/CXP platforms.
