Polarstar Kythera Semi Auto V2 M4 HPA Engine

The PolarStar Kythera SA HPA system represents a groundbreaking leap in airsoft technology, being the first mechanical HPA system from PolarStar that eliminates the need for batteries or electronics. This innovative system is designed to provide consistent, reliable performance without the vulnerabilities associated with electronic components. Named after the Antikythera Mechanism—a sophisticated ancient Greek device—Kythera embodies a similarly advanced approach to airsoft performance with its fully mechanical operation. The system’s real single-action trigger mechanism offers a tactile experience reminiscent of a true firearm, with adjustable weight and over travel for a custom shooting feel.

The Kythera SA’s design ensures a complete shot cycle with each trigger pull, enabling rapid follow-up shots and reducing the risk of double feeding. Its wide velocity adjustment range of 270 to 500 FPS, achievable by varying the operating pressure from 60 to 180 psi, makes it versatile enough for different airsoft roles, from CQB to long-range sniping. Additionally, the system’s efficiency is enhanced by its unique valve mechanism, which operates without a pilot valve, ensuring maximum air utilization and consistent performance. With its easy installation into standard gearboxes and a robust, waterproof construction, the Kythera SA is a revolutionary choice for serious airsoft enthusiasts.
