Version 2.1 of the hop-up alignment system, designed specifically for M4 AEG HPA replicas using:
- GATE Pulsar D2 engine (compact dual-solenoid HPA engine with integrated electronic control and design optimized for V2 gearboxes).
- MAXX Model chamber (high-precision hop-up chamber known for excellent bucking support and consistent feeding in HPA builds).
This system ensures perfect centering of the Pulsar D2 nozzle with the MAXX Model chamber, eliminating BB feeding variations and maximizing pneumatic efficiency in high-performance configurations.
