Polarstar Kythera V2

The Kythera has been the most eagerly anticipated product from PolarStar in the past decade. This HPA system is a radical departure from all previous systems that PolarStar has produced since the Kythera does not use a battery, an FCU or any type of electronics. The Kythera is completely mechanical. This means you never have to worry about charging batteries or work with delicate electronics. It also means that the system is completely waterproof. 

The heart of the AntTech KGS Series, the Polarstar Kythera boasts a realistic trigger with tunable sears, weight, and over-travel adjustment. The closed bolt system ensures each shot receives the same air volume and pressure. Nozzle dwell and output volume (effectively poppet dwell) can be tuned through fixed mechanical means.
