PolarStar Kythera SA – SR25 Edition (JG / V2.5 Gearbox)

Rein mechanische Präzision | Kein Akku, keine Elektronik | Ultimative DMR-Performance

Das PolarStar Kythera für die JG SR25 ist die perfekte Wahl für Spieler, die ein absolut zuverlässiges und wetterunabhängiges HPA-System suchen. Da das Kythera rein mechanisch arbeitet, benötigt es weder Akkus noch eine Steuerelektronik (FCU). Diese Version ist speziell für die verlängerte V2.5 Gearbox der SR25-Serie ausgelegt und bietet das authentische Abzugsgefühl eines echten Präzisionsgewehrs.

1. Mechanische Perfektion & Haptik

  • Realistisches Abzugsverhalten: Das Kythera nutzt einen geschlossenen Schusszyklus (Closed Bolt). Der Abzug bietet einen definierten Druckpunkt und einen spürbaren Reset, was es ideal für die Rolle als DMR (Dedicated Marksman Rifle) macht.
  • Wetterunabhängig: Da keine elektronischen Komponenten verbaut sind, ist das System völlig unempfindlich gegenüber Nässe, Kälte oder elektromagnetischen Störungen.
  • Einfache Abstimmung: Abzugsweg, Abzugsgewicht und der Überweg (Overtravel) lassen sich mechanisch einstellen, um das System perfekt auf Ihre Vorlieben anzupassen.

2. Spezifisch für JG SR25

  • V2.5 Kompatibilität: Dieses Kit enthält das längere Nozzle und die spezifischen Komponenten für die verlängerte Gearbox der JG SR25. Dies stellt ein perfektes Alignment zur Hop-Up Unit sicher.
  • Konstante Mündungsgeschwindigkeit: Das mechanische Ventil-Design der Kythera sorgt für eine extrem geringe Abweichung zwischen den Schüssen (Low FPS Deviation), was für präzise Trefferbilder auf hohe Distanzen unerlässlich ist.
  • Einfache Installation: Als "Drop-In"-System konzipiert, ersetzt es die kompletten Internals der Gearbox.

3. Wichtige Information: Zulassung & Gewährleistung (Deutschland)

Hinweis zum Umbau: Aufgrund der grundlegenden Veränderung des Schusssystems von ursprünglich Federdruck auf HPA-Luftdruck ist nach dem Einbau zwingend eine Neuabnahme der umgebauten Airsoftwaffe durch ein zuständiges Beschussamt erforderlich, da die ursprüngliche Zulassung (F-Kennzeichnung) durch den Systemwechsel erlischt. Der Einbau bzw. Umbau muss daher zwingend von einer autorisierten Fachwerkstatt (z. B. Büchsenmacher oder Waffenfachgeschäft) durchgeführt werden. Eine gesetzliche Gewährleistung kann nur dann gewährt werden, wenn ein offizieller Nachweis (Rechnung) über den fachgerechten Einbau sowie die erfolgte Neuabnahme erbracht wird.

Actually Cooling Pillow
Size: Queen (1 Count), Color: Original White (Cooling)
This is a really nice pillow, I was worried it would be too soft or too firm but it's just right and it's actually cooling, it feels cool every time I touch it. I've noticed an improvement in sleep since using it. Would recommend!

Repurchased in King Size – Still Love These Cooling Pillows
Size: King (2 Count), Color: Original White (Cooling), Size: King (2 Count), Color: Original White (Cooling)
After using the queen-size version of these pillows for over a year, we purchased the king-size set when we upgraded to a king mattress. Both my husband and I really like them. The cooling feature works well, and we like that each side feels different—when I run cold, I use the softer bamboo side, while my husband prefers the cooler side since he tends to sleep hot. They fit well in our king-size pillowcases and feel supportive in all sleeping positions, whether I’m on my stomach, side, or back. I also appreciate that you can remove some of the filling to adjust the firmness. The covers are washable, which makes them easy to maintain. Overall, we’re very happy with this repurchase and the long-lasting comfort.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.
