PolarStar JACK Nozzle – #4
The PolarStar JACK Nozzle #4 is a platform-specific nozzle for PolarStar JACK HPA engine installations. The JACK replaces the entire gearbox with a pneumatic HPA engine — the nozzle is the platform-specific component where the engine interfaces with the hop-up chamber. Each JACK nozzle number corresponds to a specific AEG platform or body group, and #4 is the correct nozzle specification for the platform or platforms that require it in the JACK range.
PolarStar is one of the leading HPA engine manufacturers in airsoft. For operators building a JACK HPA conversion, confirm the correct nozzle number for your specific AEG body from the PolarStar JACK compatibility chart, and select #4 if your platform requires it.
