HPA Conversion Kit F2™ V2 for M4/M16 - PolarStar

Product: HPA Conversion Kit F2™ V2 for M4/M16 - PolarStar Product description: The F2™ model is designed with a robust construction that allows for operating pressures ranging from 45psi to 145psi. This pressure range allows you to adjust the rate of fire from CQB to DMR using a single nozzle for the entire speed adjustment range. The F2™ nozzle is equipped with a pre-tensioned spring that ensures consistent load regardless of operating pressure. It is compatible with both light and heavy springs, similar to the Fusion Engine™, allowing for flexible load force adjustment. The F2 FCU, functioning as a Mini Fusion Engine, offers the same level of adjustability and performance as the Fusion Engine, but in a more compact cylinder size. The patented F2™ dual solenoid design provides functionality comparable to the Fusion Engine™, but in a more efficient and flexible package. The dual solenoids allow independent control of the nozzle and disc valve, ensuring precise control of the charging time and volume of air used. The system allows the trigger sequence to be changed for operation in both "closed bolt" and "AEG" modes. The F2™ features a new one-piece, lightweight valve design that ensures high efficiency at lower pressures and optimizes air consumption. The spring-loaded nozzle provides consistent loading, while the F2 FCU with LCD display allows for easy and accurate adjustment. Thanks to its extremely lightweight and compact design and dual solenoid construction, it is easy to switch between open and closed bolt firing.
