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 an excellent price-to-performance ratio).
- MAXX MODEL chamber (precision hop-up chamber optimized for HPA systems with excellent bucking support and consistency).
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 a solid and precise alignment between the Phoenix nozzle and the MAXX MODEL chamber, maximizing feeding consistency in compact ICS MPX/CXP platforms. Fully compatible with the original ICS lower receiver and ICS split gearbox systems.

Installation and adjustment
1. Printing and preparation
