PolarStar F2 HPA Unit - Standard FCU - Amped IGL - Multiple Options

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 Fusi
