The F1 is a high performance, universal HPA (High Pressure Air) drop-in cylinder designed to fit virtually any AEG gearbox. It is available as both a Centerline version, which will work with most common gearbox types, but it is also available in an Offset version to work with those unique gearboxes such as the V6 and V7. It replaces the original gearbox components with a programmable pneumatic system allowing for higher performance, greater reliability and complete adjustability. This allows the F1 to fill any role ranging from CQB to sniper with no additional components needed.
The F1 uses a custom solenoid designed by PolarStar and manufactured by MAC Valves. The design allows the solenoid to become an integral part of the system and not simply a switch to control gas flow. This not only makes the F1 more compact but also minimizes the dead volume inside of the system, increasing efficiency and decreasing response time.
Unlike similar systems, the F1 incorporates a dual purpose flow control system which allows for nozzle speed regulation and two stage firing through an integral check valve. The check valve system regulates nozzle speed based on the direction of movement while also controlling flow to the secondary firing point. This unique design promotes both increased cyclic rate and smoother chambering.

PolarStar Precision Airsoft was formed in January 2009 to fill a need for high quality, precision manufactured airsoft components designed for performance and longevity.
The 2011 release of the patented Fusion Engine HPA system marked a change in direction for PolarStar. The focus shifted from developing upgrade components within the constraints of existing systems to developing innovative HPA systems and accessories which replace the aging AEG technology.
PolarStar Airsoft is a division of PolarStar Engineering & Machine (PSE&M), a unique blend of tenured American toolmakers and a full service CAE/CAD/CAM (Computer Aided Engineering, Design, and Manufacturing), special crafts machine shop keeping alive our proud manufacturing heritage of “Made in the USA”. Founded in 1997, PSE&M began by servicing the automotive racing industry through the design and producing systems and components from “art to part.” Operating under the auspices of the Delaware Association of Professional Engineers, we retain a Professional Engineer (P.E.) on staff to ensure and certify all design and engineering standards are met. In addition to our own product line, PolarStar also offers engineering and manufacturing services tailored to the airsoft industry.
