Version 2.1 of the hop-up alignment system for M4 AEG HPA replicas with a V2 gearbox.
This kit is designed to combine Wolverine Inferno 2 or Wolverine Reaper 2 engines with a PolarStar HopUp chamber, creating a stable connection between the nozzle and the chamber. Proper alignment helps achieve more consistent feeding, reduce lateral movement, and maintain a more consistent seal during firing. Both the Inferno and Reaper are available for M4 configurations with V2 gearboxes; the Reaper Gen 2 features a closed-bolt design and an Air Saver system.
