Content

The 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.

The 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. The mechanism was so advanced in design that scientists have been studying it for decades to discover its purpose. The machine dates from around the end of the 2nd century B.C. and is the most sophisticated mechanism known from the ancient world. 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.

For 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. The first of these systems is Kythera SA (Semi-Automatic), the semi-auto-only variant for use in AEG gearboxes.

So, what makes the Kythera so unique?

Realistic Trigger

What sets this system apart from other mechanical systems is the design of its trigger. 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.

Complete Shot Cycle

The design of the Kythera SA completes a shot cycle on the trigger pull. This gives you the proven closed bolt performance of the Fusion Engine and F2 in a completely mechanical, waterproof system with a realistic trigger. It does not require the trigger to be released before the nozzle chambers the next round and the firing volume is refilled. This occurs automatically and consistently every shot, with adjustable nozzle dwell and return speed. As the system resets and recharges immediately after firing, it is ready to fire again before the trigger has been released. This means the system can cycle very quickly for faster follow up shots and a lower potential for double feeding.

Extremely Efficient and Consistent

The valve design of the Kythera operates without the need for air to control the opening or closing of the valve. 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.

Universal Charging Cord

The 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.

Easy Installation

The Kythera SA system installs into a standard gearbox as a single assembly and typically does not require any modification to the gearbox. There are no separate parts to install and the only parts needing to be retained from the gearbox is the trigger, spring guide, selector and safety components.

Wide Velocity Adjustment Range

The Kythera has a wide operating pressure range of 60psi to 180psi which allows you to fine tune the velocity of the system and tailor for different requirements and applications. Within this pressure range we observed a muzzle velocity of 270 - 500fps w/ .20g using a 6.05x380mm barrel. This lets a single Kythera be used in any role ranging from CQB to Sniper by mainly just adjusting the input pressure from your air rig.

  • Designed from the ground up as a high performance mechanical HPA system, not a modification of a solenoid operated design.
  • Patent pending valve mechanism provides excellent efficiency and consistent velocity combined with a realistic trigger pull and reset.
  • Completes a full shot cycle on the trigger pull alone which translates into consistent nozzle movement and rapid follow up shots.
  • Adjustable trigger. Adjustments include: Weight, length of pull and over travel.
  • Adjustable nozzle dwell/return speed.
  • Wide operating pressure range of 60 to 180psi.

Please note that instaling a HPA drop in system is recommanded for skilled gunsmith only. The product comes as a spare part and does not come with installation manual. By purchasing an HPA system you take entire responsability of the assembly and upcoming results. For products delivered with a trigger board, contactors / switch are not guaranted by the manufacturer in case of break. We advice to take extreme care when installing the selector plate in order to not break the button. Regarding the trigger switch, it is recommended to block mecanicaly the trigger once the the trigger switch is activated to avoid excessive pressure on it.

Bought it for a SR25 made by East Crane (EC-903). Fits perfectly, will test it after I get the proper barrel and bucking. The price was discounted, so what more can I say? Thanks.

English below.Kit commandé le 01/08, reçu le vendredi 04 après des déboires avec DPD et l'aide de Powair6. Installé le lendemain aucun soucis à déclarer. La détente est un peu dure mais pour un DMR on a pas besoin d'une grosse cadence.Conclusion, il part à BW avec moi la semaine prochaine.Kit ordered thuesday 04/08, received the next friday after some trouble with DPD shipoing resolved with Powair6 help. Installed the next day, no problem expect the trigger who's a little hard. But DMR don't need high ROF. Tester and approved, the replica come with me to BW next week.

Incroyable
j'ai acheté le pack air SMR 200+ligne US rouge+0.8 balistyk et franchement pour mon premier kit hpa monté sur mon aap01 je suis super content, tout fonctionne parfaitement ! c'est pas la première fois que je commande et je n'ai jamais été déçu. merci encore p6 à bientôt

The Balystik line have two female couplers that stops air immediatly when disconnecting, one located at the end of the regulator, the other one is at the end of the line, so you can disconnect your gun and keep your line under pressure, you can also disconnect the line from the regulator and keep the regulator under pressure. the connect / disconnect system is ultra fast, reliable and save air consumption. All is included to connect a regulator with 1/8 NPT female thread to 6mm macroline of HPA systems like Wolverine, Polarstar, Valken HPA gearbox. Max pressure input 180 PSI.

Polarstar Jack pack
This is a pretty good package for HPA I thinkThe only problem I had was my air regulator getting damaged. It was almost impossible to set 1 joule as the psi gauge needle was constantly moving and leaking a small amount of air out of the regulator but if that wasn't the case I would really recommend itAll of these things happened on my first game with gameBut somehow we managed to make it work so I can play, I just need to refill my HPA tank more oftenSo if I could get a working replacement regulator I would give 5 stars
