Version 2.1 of the hop-up alignment system, designed specifically for M4 AEG HPA replicas using:
- Redline N7 Milsim G2 engine (second-generation compact HPA engine optimized for milsim configurations with excellent pressure control and response).
- Begadi Neptune Pro chamber (high-precision hop-up chamber with micrometric adjustment system and geometry optimized for HPA).
This system ensures perfect centering between the N7 G2 nozzle and the Neptune Pro chamber, eliminating BB feeding variations and maximizing pneumatic flow efficiency in high-performance builds.
