Version 2.1 of the hop-up alignment system, designed specifically for M4 AEG HPA replicas using:
- Redline N7 Milsim G2 engine (second-generation modular HPA engine optimized for high-performance milsim configurations).
- Bullgear 2024 chamber (next-generation hop-up chamber optimized for HPA systems, providing improved bucking stability and better feeding control).
This system ensures perfect centering between the N7 G2 nozzle and the Bullgear 2024 chamber, eliminating feeding variations and maximizing the efficiency of the pneumatic system in high-rate-of-fire configurations.
