HPA Conversion Kit F2(TM)
F2(TM) is essentially a mini version of the HPA Fusion Engine(TM), retaining all its advantages in a smaller and more flexible package. Thanks to the dual solenoid system, it allows independent control over BB loading time and air volume for the shot, making it suitable for both closed bolt (locked bolt) and AEG modes. The entire system is extremely lightweight, and its compact design allows adaptation to various configurations and weapons. Available in different variants for various gearboxes. Additionally, with interchangeable nozzles, a single system can be used across multiple gun types.The conversion kit includes a spring-loaded nozzle, ensuring consistent feeding force regardless of operating pressure. The FPS adjustment range is 60 to 150 m/s (205 – 500 FPS) at an operating pressure of 45 to 145 PSI.
