    Product Description

    The manufacturer of this product enforces a strict minimum advertised price (MAP) policy which excludes this product from any additional discount coupon codes.

    PolarStar - F2 417 Conversion Kit for VFC HK417 (Standard FCU)

     

    F2 is essentially a Mini Fusion Engine. It offers the same adjust-ability and performance as the Fusion Engine in a cylinder sized package.

    Patented Dual Solenoid Design

    The dual solenoid design of the F2™ provides the same functionality as the legendary Fusion Engine™ but in a more compact, efficient and flexible design. Dual solenoids allow for the nozzle and the poppet valve to be adjusted independently of each other for unparalleled control over both the loading time and air volume used. Additionally, this makes it possible to change the firing sequence giving it the ability to operate in both true closed bolt as well as "AEG" mode.

    Increased Efficiency

    The F2™ incorporates a new one-piece, lightweight poppet valve design yet still operates on the same principle as the Fusion Engine™ poppet. This valve is able to operate at lower pressures and uses less air volume to function which optimizes air efficiency.

    The standard F2 poppet is equivilent to the Red Low-Flow poppet of the Fusion Engine.

    The robust design of the F2™ allows for an operating pressure range of 45psi to 145psi which enables it to achieve velocities from CQB to DMR while employing only one nozzle for the entire velocity adjustment range. 

    Spring Loaded Nozzle

    The F2™ nozzle is spring biased forward which provides a consistent loading force regardless of operating pressure. It shares the same spring as the Fusion Engine™ with both light and heavy spring options available to adjust the loading force. 

    Complete Tuning Control

    The F2™ comes complete with a Fire Control Unit (FCU) that has an LCD display that allows you to tune your F2 to your liking! Adjust it's dwell, rate of fire, burst modes, nozzle feeding, and more!
