PolarStar F2 HPA Engine – SR25 / A&K Edition (DE Version / Semi-Only)

Maximale Reichweite | Dual-Solenoid Präzision | Rechtssichere Semi-Konfiguration

Die PolarStar F2 ist das ideale Upgrade für SR25-Systeme, die als präzise DMR (Designated Marksman Rifle) eingesetzt werden. Durch das kompakte Cylinder-Drop-In Design wird die mechanische V2.5 Gearbox durch ein hocheffizientes Dual-Solenoid-System ersetzt. Diese spezielle DE-Version ist technisch dauerhaft auf Einzelschuss (Semi-Auto) limitiert, um den gesetzlichen Anforderungen in Deutschland für Waffen über 0,5 Joule zu entsprechen.

1. DMR-Performance auf höchstem Niveau

  • Dual-Solenoid Technologie: Die F2 nutzt zwei unabhängige Magnetventile, um Nozzle-Bewegung und Luftabgabe getrennt zu steuern. Dies garantiert eine unerreichte Konstanz der Mündungsgeschwindigkeit – essenziell für weite Trefferbilder.
  • Spezielles SR25 Nozzle: Dieses Kit enthält das verlängerte Nozzle, das exakt auf die V2.5 Spezifikationen der A&K SR25 (und baugleiche Modelle) zugeschnitten ist, um ein perfektes Alignment zum Hop-Up sicherzustellen.
  • Closed-Bolt Modus: Wie das Flaggschiff Fusion Engine kann die F2 im Closed-Bolt Modus betrieben werden, was die Präzision durch einen statischen Ladevorgang vor der Schussabgabe maximiert.

2. Effizienz & Anpassbarkeit

  • Hocheffizientes Ventil-Design: Die F2 arbeitet extrem luftsparend, was trotz des langen SR25-Laufs für eine hohe Schussausbeute pro Flaschenfüllung sorgt.
  • Vollständig Programmierbar: Über die mitgelieferte FCU lassen sich Parameter wie Poppet-Dwell und Nozzle-Delay individuell auf das verwendete BB-Gewicht und das Hop-Up Gummi abstimmen.
  • CNC-Fertigung: Das Gehäuse besteht aus hochfestem Aluminium und bietet maximale Stabilität bei minimalem Eigengewicht.

3. Wichtige Information: Zulassung & Gewährleistung (Deutschland)

Hinweis zum Umbau: Aufgrund der grundlegenden Veränderung des Schusssystems von ursprünglich Federdruck (AEG) 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.

Perfect for Adding Privacy to a Piano Studio
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
I Ordered the 2 Panel version which is way too big for my needs... that's on me. So keep in mind that the picture shows a fabric made for two panels only being used on one and hence it is not pulled tight; it would pull tight and not be so wrinkly if it was set up properly as two panels. The metal pools that make up the panels seem to be well made, stable, and of good quality. They were very easy to put together and they stand up tall with plenty of height. The appearance of it with the fabric on it isn't as elegant as it could be, but it still looks good enough. The material is plenty solid, not allowing light through it, and thereby making a solid barrier. I am using it to block the view out the studio door when a student is sitting at the piano to avoid distractions from the hallway. It will allow a student to enter the studio with our distracting the student who is at the piano.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room. The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams. The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money. What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.

Trouble hanging
Color: White - 2 Doors
This was easy to assemble, just the right size. The only thing was the way it was hung on wall, very hard to measure the right height.
