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. \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe name \"Kythera\" (ky-the-ra) was derived from the Antikythera Mechanism which is a mysterious device that was discovered by sponge divers off the coast of the Greek island Antikyther.

Nothing as complex is known for the next thousand years. The Antikythera Mechanism is now understood to be dedicated to astronomical phenomena and operates as a complex mechanical \"computer\" which tracks the cycles of the Solar System.\u003c\/p\u003e\n\u003cp\u003eFor this reason we used the name Kythera for the valve mechanism at the core of a new line of PolarStar mechanical HPA systems. Although it contains very few parts and is easy to install and maintain, the system incorporates a very intelligent design and is unlike anything else on the market. The system was designed as a mechanical system from the ground up and uses a realistic trigger mechanism which can be applied to single-shot, semi-automatic and fully-automatic systems.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe first of these systems is Kythera SA (Semi-Automatic), the semi-auto-only variant for use in AEG gearboxes.

The trigger mechanism is designed to replicate the function, weight and feel of a real single-action firearm trigger. It feels real because it is real. The hardened alloy steel sears catch and release the stainless steel spool valve in the same way the sears of a real firearm catch and release the hammer or striker. This gives the Kythera trigger the distinct break and reset you would expect to feel when firing a real single action firearm. The trigger mechanism in the Kythera SA is also adjustable, allowing the user to fine tune the weight and over travel. Additionally, the internal firing valve is balanced and the only force applied during firing is the main spring. This means the function and feel of the trigger is independent of input pressure and velocity.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/7466\/4301\/files\/IMG_2701.jpg?v=1582664307\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eComplete Shot Cycle\u003c\/h2\u003e\n\u003cp\u003eThe design of the Kythera SA completes a shot cycle on the trigger pull.

Without a pilot valve, 100% of the air going into the system is fired through the nozzle allowing it to operate very efficiently. In addition to being extremely efficient, the system is also extremely consistent. The valve is released at the same point every shot with the same force applied, regardless of trigger input.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0023\/7466\/4301\/files\/IMG_2698.jpg?v=1582664360\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eUniversal Charging Cord\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eThe steel cord visible at the back of the system is attached to a cocking mechanism for the internal spool valve.  Although the system automatically cocks the spool valve when the system is pressurized, since the Kythera uses a balanced valve, it is possible in certain situations that the valve could stall and needs to be manually cocked. This typically only happens if the system is run completely out of air so that the pressure drops below the operating range of the system. The cord is designed to be either routed through the grip of the rifle for easy access or even possibly attached in some fashion to the charging handle.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eEasy Installation\u003c\/h2\u003e\n\u003cp\u003eThe Kythera SA system installs into a standard gearbox as a single assembly and typically does not require any modification to the gearbox.

With the exception of the poppet being integral to the nozzle, the valve is similar to the poppet valve used in the previously released Fusion Engine and is what gives JACK its signature muzzle report. The system itself only has 6 parts and can be completely disassembled by hand in a matter of seconds so the system is very reliable and easy to maintain.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eJust like all other PolarStar HPA conversions, JACK also allows for easy velocity adjustment. Using a standard M4 as an example, velocity can be adjusted from below 280fps and up to approximately 500fps with a .20g BB. This can be done simply by adjusting input pressure and poppet dwell to fine tune your rifles velocity in increments of just a few FPS at a time. Maximum velocity potential of the system will vary depending upon the barrels length and tightness of the bore.

It’s a hop up, or a paperweight, or maybe a very expensive fidget spinner, but we’re pretty sure it’s a hop up. Actually, it's a 6061 T6 Aircraft Aluminum hop up. We know, \"Aircraft Grade\" is the favorite buzzword of every airsoft company trying to make a $15 part sound like it belongs on a SpaceX rocket. But we actually machine these Things in-house at PolarStar to +\/- 0.002\" tolerances because we’re tired of seeing high-end builds ruined by sloppy, off-spec cast parts. They used this stuff for wing spars and fuselage skins, and now you’re using it for your hop up. It’s probably overkill, but \"overkill\" is basically our middle name.\u003c\/p\u003e\n\u003cp class=\"p3\"\u003eLook, we could play the industry game and trademark some stupid marketing words or pay a YouTuber to tell you this Thing will magically double your range while they shill you a generic flashlight. PolarStar don’t play that. We designed this with a zero-BS focus on the stuff that actually matters: consistency, fitment, and air-seal. No fluff, no \"proprietary magic,\" just a straight-forward, precision-engineered tool that does exactly what it’s supposed to do every time you pull the trigger.\u003c\/p\u003e\n\u003cp class=\"p3\"\u003eThe heart of this Thing is our TDC (Top Dead Center) slider system. Unlike the old-school sliders that shift if you sneeze on them, our TDC arm applies perfectly vertical pressure for a consistent flight path. \u003c\/p\u003e\n\u003cp data-path-to-node=\"0\"\u003eWe’ve modularized the design so you can actually tune the fitment for both AEG and HPA builds. While we have some serious upgrades in the works—like interchangeable gearbox lips to kill \"mid-cap syndrome\" and barrel slot wing bushings to eliminate rotational wobble—those will be available for purchase down the line as optional accessories. For now, we've focused on the core essentials. If your hop up is snug and your nozzle is centered, your gun shoots straight. It’s not rocket science; it’s just good engineering.\u003c\/p\u003e\n\u003cp class=\"p3\"\u003e\u003cb\u003eSPECS:\u003c\/b\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003e\u003cb\u003eCompatibility:\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eStandard V2 M4\/M16 models (AEG and HPA)\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003e\u003cb\u003eMaterial:\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003e100% Machined 6061 Aluminum\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003e\u003cb\u003eAdjustment:\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eTDC Slider System (3x4mm nub compatible)\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cspan class=\"s1\"\u003e\u003c\/span\u003e\u003cb\u003eColor:\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eBatch 01 - Medical Metal Gray\u003c\/li\u003e\n\u003cli class=\"li3\"\u003e\n\u003cb\u003eManufacturing:\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"p3\"\u003e\u003cb\u003eWHAT’S IN THE BOX?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"p3\"\u003eThe hop up Thing and the parts to make it work.
