Version 2.1 of the hop-up alignment system, specifically designed for M4 AEG HPA replicas using:
- Wolverine Reaper 2 / Inferno 2 engines (compact HPA engines with high pneumatic efficiency and plug & play configuration).
- Silent Industries ALPHA M4/16 AEG/HPA chamber (CNC chamber with TRUE-TDC system, tension ring, and full bucking lip support optimized for HPA).
This version of ALPHA is from before 2026; the body is rounded.
This kit provides precise alignment between the Reaper 2 / Inferno 2 nozzle and the ALPHA chamber, controlling bucking pressure and preventing typical HPA issues such as double feeding or BB loading inconsistencies.
