Take a look at the Ares Airsoft Walther 2000 that is equipped with the PolarStar Kythera Engine which is the Swamp Sniper's dream airsoft rifle. The ARES airsoft version is a precise replica of the spring-powered rifle, complete with a similar bipod for stationary deployment, enhancing accuracy. It also features dummy rounds for the magazine, adding to its realism.

Kythera, the valve mechanism at the heart of PolarStar's new line of mechanical HPA systems, is a uniquely designed, easy-to-install and maintain system with few parts, featuring a realistic trigger mechanism applicable to single-shot, semi-automatic, and fully-automatic systems, with the first variant being the semi-automatic Kythera SA for use in AEG gearboxes.
