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.
