Designed specifically for Ver.2 M4 gearboxes, this revolutionary HPA (High-Pressure Air) system breaks away from traditional electro-pneumatic designs and instead delivers a purely mechanical, battery-free solution that combines advanced engineering with intuitive function.\u003c\/p\u003e\r\n\u003cp data-start=\"466\" data-end=\"1072\"\u003eUnlike most HPA systems that rely on solenoids and FCUs (Fire Control Units), the Kythera was engineered from the ground up as a mechanical unit. This means no electronics, no batteries, and full waterproof capability — ideal for players who operate in all conditions and demand absolute dependability. At the heart of the Kythera is a patent-pending, balanced valve mechanism that provides a clean, efficient air cycle with consistent velocity and minimal air waste. Every trigger pull results in a full shot cycle, delivering rapid follow-up shots and superior nozzle reset for closed-bolt-like accuracy.\u003c\/p\u003e\r\n\u003cp data-start=\"1074\" data-end=\"1602\"\u003eOne of the standout features of the Kythera SA is its incredibly realistic trigger design. Inspired by real firearm mechanics, this trigger uses hardened alloy steel sears to catch and release the internal stainless steel spool valve. The result is a crisp, responsive trigger with an authentic break and reset — a feature rarely found in the airsoft world. The trigger system is also fully adjustable for weight, travel, and over-travel, allowing users to fine-tune their setup for precision shooting or high-speed engagements.\u003c\/p\u003e\r\n\u003cp data-start=\"1604\" data-end=\"2112\"\u003eInternally, the Kythera is simple yet sophisticated. It completes a shot cycle entirely upon trigger pull, which means you never have to release the trigger for the system to re-cock or chamber the next round. This also prevents double feeding and ensures a smooth, consistent firing experience every time. Additionally, the nozzle dwell and return speed can be adjusted to suit different build configurations, ammo types, or field roles — whether you're building a CQB rifle or a long-range sniper platform.\u003c\/p\u003e\r\n\u003cp data-start=\"2114\" data-end=\"2438\"\u003eWith a wide operating pressure range of 60 to 180 PSI, the Kythera allows users to dial in velocity from approximately 270 to 500 FPS using .20g BBs and a 6.05x380mm barrel. This versatile adjustment range makes the Kythera suitable for nearly any style of play, from indoor close-quarters to long-range outdoor engagements.\u003c\/p\u003e\r\n\u003cp data-start=\"2440\" data-end=\"2746\"\u003eAnother game-changing feature is the universal charging cord. While the system is designed to auto-cock when pressurized, the steel cable can be routed through the pistol grip or connected to the charging handle for manual cocking if necessary — typically only when the system has been fully depressurized.\u003c\/p\u003e\r\n\u003cp data-start=\"2748\" data-end=\"2993\"\u003eInstallation is incredibly straightforward. The Kythera is a drop-in system for Version 2 gearboxes and typically requires no gearbox modifications. Just retain your selector, safety components, spring guide, and trigger, and you're ready to go.\u003c\/p\u003e\r\n\u003cp data-start=\"2995\" data-end=\"3337\"\u003eThe Kythera SA is not just another HPA system.

This can be from the manufacturer designing the rifle differently, or from the thickness of the gearbox shell affecting how far from the hop-up chamber the cylinder sits. Therefore one nozzle length may work in different rifle models but not necessarily work in the same model from a different manufacture. For example, a standard MP5 could require any of 4 different nozzle lengths depending on the manufacturer.\u003cbr\u003e\u003cbr\u003eFor this reason we produce numerous different nozzle lengths to provide compatibility for a wide range of replicas. Below we are listing the make and model of the replicas which the nozzle length is most commonly used with but it may be compatible with more models. For a list of replicas which we have measured and calculated the compatible nozzle length, please visit our Help Center.\u003cbr\u003e\u003cbr\u003eOnce you determine what number nozzle your replica requires, that number is universal across all engines* that use the numbered nozzle system. So, if you determine your replica takes a #11 JACK nozzle, then it will also take a #11 Kythera or F2 nozzle if you ever put a different system into it.\u003cbr\u003e\u003cbr\u003e*NOTE: The Kythera models which are made for a specific replica (e.g. A\u0026amp;K\/JG SR-25) with a non-standard length cylinder will use a specific nozzle with a \"K\" prefix. Since they use a non-standard cylinder, the universal nozzle numbing system cannot be used for these models. However, the design and profile of the \"K\" nozzles are the same as the standard numbered nozzles and are cross compatible between standard and non-standard cylinders.\u003cbr\u003e\u003cbr\u003eAdditionally, all nozzles are marked with their number with the exception of the #1 nozzle. These are produced in far greater quantities than all of the other nozzles so they are left unmarked to reduce production time.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eManufacturer: PolarStar\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eSpecifications:\u003c\/p\u003e\u003cp\u003eCompatibility: Polarstar Kythera HPA Engines.

No pilot valves are used, and the valve releases at the same point and force every shot — a design that yields both efficiency and predictable performance.\u003c\/p\u003e\r\n\u003cp data-start=\"2196\" data-end=\"2727\"\u003e\u003cstrong data-start=\"2196\" data-end=\"2254\"\u003eAdjustable dwell, nozzle speed and wide pressure range\u003c\/strong\u003e\u003cbr data-start=\"2254\" data-end=\"2257\"\u003eTuning is straightforward and flexible.
