Choose PolarStar and you are choosing one of the most advanced propulsion systems in airsoft. By replacing the mechanical parts of a traditional gearbox with an electro-pneumatic "engine", you get a level of performance a standard AEG physically cannot match. We specialise in PolarStar because serious players demand the extreme trigger response and the near-endless adjustment options that PolarStar delivers.
Choose the right engine for your mission
PolarStar offers different systems depending on your needs and budget:
Fusion Engine: The original and most robust solution. The entire gearbox is replaced with a complete PolarStar unit, giving maximum stability and the widest range of adjustment.
F2: The "little Fusion Engine". A drop-in kit that fits inside your existing gearbox but uses the same dual-solenoid technology as its big brother, for very high air efficiency and precision.
Jack & F1: Ideal entry-level HPA engines. They are compact, easy to install and turn your VFC or G&G rifle into a high-performance machine.
Full control via the FCU
What sets PolarStar apart is the Fire Control Unit (FCU). This small computer puts you in charge of your rifle:
Adjustable rate of fire (ROF): You decide whether your rifle fires 10 or 50 rounds per second.
Dwell settings: Tune the volume of air precisely to your barrel length for maximum air efficiency.
Burst modes: Programme your rifle to fire 2, 3 or 5-round bursts with a single pull.
Maintaining your PolarStar system
One of the biggest advantages of PolarStar is minimal maintenance, as there are almost no moving parts:
Clean air matters: Always use clean HPA tanks and a high-quality regulator.
Lubrication: The system only needs a tiny amount of special grease on the O-rings now and then. You will find everything you need in our airsoft cleaning and maintenance collection.
Battery check: Keep the small LiPo battery for the FCU charged with a quality charger.
