Polarstar Airsoft F1 HPA Engine V2/M4
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.

While the sport of Airsoft is designed to be enjoyed by all ages, ignoring proper safety practices can turn a day of fun into a tragedy. Todays modern airsoft guns are capable of firing a BB at velocities that can and will penetrate fabric and skin, causing serious injury. Always wear "Full Seal" eye protection and observe proper weapon handling practices such as keeping the weapon on "safe" and cleared with the magazine out to prevent accidental discharge. REMEMBER!! Safety begins with the shooter!!
