Polarstar M4/M16 JACK V2 Conversion Kit - Mini FCUs

  • $324.95

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
  • Plugboards for machine guns or custom installs
