icon Description

The JACK™ was designed to answer the demand for an affordable, high-performance HPA (High-Pressure Air) conversion for AEG’s. The system is a drop-in cylinder replacement that is universally compatible with a wide range of gearbox versions that have centre-line nozzles.

Similar to its sister products, the JACK™ replaces the original gearbox components with a programmable pneumatic system allowing for higher performance and greater reliability over a gear-driven system. Although economically priced, the JACK™ still retains the same performance and quality you have come to expect from PolarStar products.

The JACK™ has only one moving part, the nozzle, which acts as its own poppet valve. Similar to the Fusion Engine™ and F2™ poppet, the nozzle is only piloted by the solenoid to open air flow through the poppet with none of the firing air coming from the solenoid itself. This design lets the JACK™ send a higher flow of air down the barrel than systems that only use a solenoid as the firing valve.

**All kits come with an FCU, Switchboard, Wire Harness and any additional components needed to convert the specific airsoft rifle model for which the kit is configured. The HPA Tank, Air Rig (regulator/line/QD fitting) and Battery needed to operate the system are purchased separately.

***If you do not purchase a custom braided grip line, you will need to purchase a Blaystik male nipple for macro line to enable you to connect to your main line.
