Version 2.1 of the hop-up alignment system, designed specifically for M4 AEG HPA replicas using:
- REDLINE N7 MILSIM G1 engine (compact and modular HPA engine designed for milsim configurations with linear response and low air consumption).
- MAXX Model chamber (hop-up chamber optimized for HPA systems, with precise adjustment and compatibility with high-speed nozzles).
This system ensures perfect centering between the nozzle and the chamber, preventing feeding variations and improving the overall efficiency of the pneumatic system.
The kit replaces the original hop-up adjustment wheel with a thinner version that remains fully functional, optimized for the N7 + MAXX configuration.
