List of products by brand Polarstar

PolarStar Airsoft is the pioneering American industry leader in High Pressure Air (HPA) technology for airsoft. Renowned for inventing the game-changing Fusion Engine, as well as the versatile F2, JACK, and mechanical Kythera drop-in systems, PolarStar engineered the standard for instant trigger response, programmable rate of fire, and pinpoint velocity consistency.

Designed, engineered, and manufactured in the USA, PolarStar Airsoft revolutionized the airsoft industry by introducing electro-pneumatic High Pressure Air (HPA) technology to modern tactical gameplay.

Industry-Defining HPA Performance

PolarStar set the benchmark for pneumatic airsoft systems with its iconic Fusion Engine and lightweight cylinder conversion drops-in like the dual-solenoid F2 and single-solenoid JACK. By eliminating traditional mechanical gearbox wear, PolarStar systems offer infinite adjustability over velocity (FPS), rate of fire (ROF), and nozzle dwell through programmable FCUs (Fire Control Units).

Mechanical Innovation & CO2 Integration

Expanding beyond electronic control, PolarStar introduced the Kythera—a fully mechanical, waterproof HPA system engineered for realistic single-action trigger pulls without batteries. Combined with their ultra-compact Micro Regulators and stock-integrated air systems (CGS/UGS), PolarStar delivers unmatched reliability and streamlined ergonomics.
