PolarStar JACK V2 (Mini FCU) Conversion Kit, M4/M14

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

Similar to its sister product, the F1, it 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, JACK still retains the same performance and quality you have come to expect from PolarStar products.
