Version 2.1 of the hop-up alignment system, specifically designed for M4 AEG HPA replicas using:
- Gate Pulsar-H motor (high-power compact HPA engine with integrated electronic control system).
- Silent Industries ALPHA M4/16 AEG/HPA chamber (precision CNC chamber with TRUE-TDC system and lip tension ring optimized for HPA).
This version of ALPHA is from before 2026; the body is rounded.
This kit ensures perfect alignment between the Pulsar-H nozzle and the ALPHA chamber, eliminating double feeding issues and maximizing the efficiency of the pneumatic system. The configuration takes advantage of the direct response of the Pulsar-H and the precise geometry of the ALPHA for exceptional shot-to-shot consistency.
