Version 2.1 of the hop-up alignment system, designed for M4 AEG HPA replicas using:
- SparkLabs WOLF engine (compact high-performance HPA engine designed for M4 V2 builds).
- Silent Industries ALPHA M4/16 AEG/HPA chamber (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 precise alignment between the WOLF nozzle and the ALPHA chamber, eliminating feeding variations and maximizing shot-to-shot consistency. It is especially compatible with ICS split designs.
