P* F2™ HPA Conversion Kit Classic Army KAC LMG - Red

Polarstar F2™ HPA Conversion Kit for Classic Army KAC LMG

Looking for a high-end and stable HPA system for AEG gearboxes? Want a universal setup with interchangeable nozzles for different replicas? Need adjustable velocity usable indoors as well as on large outdoor fields? Then the Polarstar F2™ is the best tool for the job. It is essentially a mini version of the Fusion Engine™ HPA system, keeping all its advantages in a more compact and flexible package. Thanks to the Dual-solenoid system, the loading time and air volume can be adjusted independently, enabling operation in both closed-bolt and AEG modes. The entire unit is extremely lightweight, and its compact construction allows use in multiple platforms. It is available in versions for various gearboxes. Interchangeable nozzles also allow one system to be adapted to multiple replicas. The kit includes a spring-loaded nozzle, ensuring consistent feeding force across the entire PSI range. Velocity can be tuned from 60 to 150 m/s (205–500 FPS) at an operating pressure of 45 to 145 PSI.
