101Tech USA are distributors for PolarStar Airsoft and they are now taking pre-orders for the Polarstar Kythera which is a Semi-Auto system for V2-M4 airsoft guns... "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.
