Polarstar Kythera SA Semi Auto Mechanical HPA Drop-In Conversion Kit
For an HPA build focused on a mechanical trigger experience, the PolarStar Kythera SA takes a different route from electronic engines. It runs semi-auto without a firing battery or FCU, using a mechanical break and reset. Choose the version for your gearbox and nozzle requirements, then build the regulated air setup around the host.
Key Features
- Mechanical trigger break and reset
