Polarstar M249 JACK Conversion Kit - Mini FCUs
The patent-pending JACK™ system 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 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 is driven system. Although economically priced, JACK™ still retains the same performance and quality you have come to expect from PolarStar products.
Switchboard is already available or in production for a wide range of models with even more on the way, including:
- Version 2
- Version 3
- ARES Amoeba
- Elite Force HK417
- Elite Force Tavor (S&T)
- ARES V2/V3
