PolarStar Kythera HPA Conversion Kit (V2 / V3, Semi-Auto ONLY) Style:V2/M4 a fully functional Minigun styleThe Kythera has been the most eagerly anticipated products 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.
