Version 2.1 of the hop-up alignment system, designed specifically for ICS MPX/CXP HPA replicas using:
- Blackdraft Phoenix engine (compact and efficient HPA engine, ideal for subcompact SMG configurations).
- BEGADI Neptune PRO chamber (CNC hop-up chamber with precise adjustment system and excellent bucking support for HPA).
This kit ensures solid alignment between the Phoenix nozzle and the Neptune PRO chamber, optimized for the compact ICS MPX/CXP platform. It is fully compatible with the original ICS lower receiver and other universal lowers from the project.
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.
