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

Maximale Zuverlässigkeit | Bewährte Single-Solenoid Technik | Rechtssichere Semi-Konfiguration

Die PolarStar JACK ist der ideale Einstieg in die Welt der High-End HPA-Systeme. Als kompaktes Cylinder-Drop-In Kit ersetzt sie die internen Komponenten Ihrer mechanischen V2.5 Gearbox durch ein leistungsstarkes Single-Solenoid-System. Diese spezielle DE-Version für die A&K SR25 ist technisch dauerhaft auf Einzelschuss (Semi-Auto) limitiert, um den gesetzlichen Anforderungen in Deutschland für Waffen über 0,5 Joule zu entsprechen.

1. Performance & Effizienz

  • Vielseitiges Single-Solenoid Design: Die JACK arbeitet mit einem einzigen Magnetventil, das sowohl den Nozzle-Zyklus als auch den Luftstrom steuert. Dies macht das System extrem wartungsarm und einfach in der Handhabung.
  • Spezielles SR25 Nozzle: Dieses Kit enthält das verlängerte Nozzle, das exakt auf die V2.5 Spezifikationen der A&K SR25 und baugleicher Modelle zugeschnitten ist, um ein perfektes Alignment zum Hop-Up sicherzustellen.
  • Hohe Kompatibilität: Trotz der einfachen Bauweise bietet die JACK eine beeindruckende Konstanz der Mündungsgeschwindigkeit, was sie zur perfekten Wahl für ein zuverlässiges DMR-Setup macht.

2. Integration & Kontrolle

  • Einfache Installation: Da das System aus nur wenigen beweglichen Teilen besteht, ist die JACK besonders robust und unanfällig gegenüber Umwelteinflüssen.
  • Vollständig Programmierbar: Über die mitgelieferte Fire Control Unit (FCU) lassen sich alle wichtigen Parameter wie Dwell-Zeiten und Nozzle-Timing individuell auf das verwendete BB-Gewicht und den Lauf abstimmen.
  • Sofortiges Ansprechverhalten: Die elektropneumatische Auslösung sorgt für einen extrem kurzen Trigger-Weg und eine unmittelbare Schussabgabe ohne die Trägheit eines Motors.

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.

A total game changer (where were these when I was a teen?!)
Size: 72 Count (Pack of 1)
I honestly wish these had been around when I was younger! The Mighty Patch Original is hands-down the most effective way I’ve found to deal with stubborn whiteheads. Instead of picking at my skin and making things worse, I just pop one of these on at night and let it do the work while I sleep. By the morning, you can actually see the gunk it pulled out right on the patch (gross, but strangely satisfying). It significantly reduces the size and redness of the zit in just one use, and because it covers the spot, it stops me from touching it and causing more irritation. The 72-count pack is a great value and lasts quite a while. They stay put all night, even if you toss and turn, and they’re clear enough that you almost forget you’re wearing them. If you’re looking for a stress-free way to clear up your skin overnight, these are a must-have!

Works on all skin types
Size: 36 Count (Pack of 1)
What an amazing product! I'm in my 40s and still experience occasional acne. I purchased Mighty Patch, and after wearing it overnight, my blemish was noticeably cleared up by morning. I have fairly dry skin and already use quality skincare products both morning and night, so I was impressed by how well it worked. My 17-year-old son also tried one when he started getting a few breakouts, and it cleared up his blemish as well. His skin is much oilier than mine, which shows that this product can be effective for both dry and oily skin types. I’m very happy with the results and will definitely be purchasing it again!

Doesn't replace good hygiene efforts
Size: 36 Count (Pack of 1)
It's not a miracle patch if that's what people are buying it for. The patch, once skin has been cleansed and dried, adheres well and stays put overnight. The patch does pull out dead white cells but never has it been one patch and done. I am finding that another patch has to go on to the blemish as it's now open and very red. So depending on how big the blemish is, determins how many patches you will need to fully clear up. On a great note: It does help with preveting me from touching it or picking at it which does indeed help the blemish heal faster. I keep a box in my medicine cabinet for really big, very noticable , blemishes, but I don't find it very cost effective nor do I find that my blemishes are cleared up 100% with use. It's really more a matter of: stop touching your face with dirty hands, don't go to bed with makeup on, stop squeezing/popping white heads, invest in a good facial cleanser with proven ingredients. There is no miracle patch. It's an good product for sure, but not a miracle. It will not replace good hygeine and a good cleanser.

Another household staple. This are cheaper than the name brand but work just as good. Cotton is nice and thick, the stick holding it is sturdy.
