The PolarStar F2 HPA Conversion Kit offers top-level performance and adaptability for CA/A&K M249 series airsoft guns. Its compact and efficient design allows for a wide range of power and rate of fire adjustments, as well as the best possible air consumption.
Awarded "Best HPA Engine" at the Airsoft Players Choice Awards, the PolarStar F2 builds on the successful Fusion Engine™ design, but offers a more compact and powerful alternative. With its dual solenoid system, the F2 allows for independent adjustment of both the nozzle and poppet valve, giving you full control over the feed time and amount of air used.
The system's unique one-piece poppet valve optimizes air consumption, and its wide operating pressure range (3.1-10 bar) allows for speed control for CQB games or DMR-level power with a single nozzle. The nozzle is spring-loaded forward, ensuring consistent feed force at all pressures. In addition, the F2 can operate in closed bolt mode or "AEG mode", increasing its versatility.
The F2 is also compatible with Gel Ball systems and can be configured to their specific needs.
