HPA Conversion Kit Kythera SA V2 for M4/M16 - PolarStar

Product: HPA Conversion Kit Kythera SA V2 for M4/M16 - PolarStar Product description: Kythera SA V2 is the latest mechanical HPA system for M4/M16 weapons from PolarStar. This system is characterized by the absence of electronic components such as batteries or FCU, which ensures its full mechanical functionality and water resistance. The name "Kythera" is inspired by the Antikythera mechanism, an ancient device for tracking astronomical phenomena, known for its advanced mechanical design. Kythera SA is designed as a semi-automatic system for AEG mechaboxes, with a realistic trigger mechanism that mimics the function and feel of a real firearm. The trigger uses hardened alloy steel sears that engage and release a stainless steel coil valve, providing an authentic trigger break and reset feel. This mechanism is adjustable, allowing the user to fine-tune the trigger resistance as needed. Kythera SA ensures a complete firing cycle with a single trigger pull, thanks to a balanced internal release valve where the only force acting is the main spring. This means that the trigger function remains consistent regardless of input pressure or muzzle velocity. Overall, this system offers easy installation and maintenance, with an intelligent design that sets it apart from other mechanical systems on the market.
