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, ideal for compact SMG platforms).
- BULLGEAR chamber (reinforced hop-up chamber designed for HPA with excellent bucking support and precise adjustment).
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 BULLGEAR chamber, optimized for the compact internal geometry of ICS MPX/CXP platforms. Fully compatible with the original ICS lower receiver, maintaining the structural integrity of the ICS split gearbox system.
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.
