PolarStar JACK™ HPA Conversion Kit

Code name "Simple Jack." The JACK™ was designed to answer demand for an affordable, high-performance HPA conversion for AEGs — a drop-in cylinder replacement universally compatible with a wide range of gearbox versions that have center-line nozzles. PolarStar Filter Fitting included.

The JACK™ has only one moving part: the nozzle, which acts as its own poppet valve. Like the Fusion Engine™ and F2™, the nozzle is only piloted by the solenoid to open airflow — none of the firing air comes through the solenoid itself. This lets the JACK™ deliver higher flow down the barrel than solenoid-only firing valve designs.

Gel Ball Compatible

JACK kits can be configured for gel ball systems. Contact us for details.
