PolarStar Kythera SA Nozzle – #12
The PolarStar Kythera SA Nozzle #12 is a platform-specific nozzle for PolarStar Kythera SA HPA engine installations. Each PolarStar nozzle number corresponds to a specific AEG body or platform group that requires that nozzle’s length and geometry for correct BB feed and hop-up interface. Using the wrong nozzle number causes feeding failures regardless of engine quality — the nozzle number must match the target body.
PolarStar is one of the leading HPA engine manufacturers in the airsoft industry. For operators building a Kythera SA HPA conversion, confirm the correct nozzle number for your specific AEG body from the PolarStar nozzle compatibility chart before ordering, and select this #12 if your platform requires it.
