Version 2.1 of the hop-up alignment system, designed for M4 AEG HPA replicas using:
- GATE Pulsar-S engine (compact HPA engine with integrated electronics and precise trigger control).
- RETROARMS chamber (high-precision hop-up chamber with excellent bucking support and fine adjustment capability).
This kit ensures perfect centering between the Pulsar-S nozzle and the RETROARMS chamber, eliminating lateral play and improving feeding consistency in HPA configurations. Fully compatible with ICS split systems and V2 gearboxes.
