Polarstar Jack™ Nozzle #2 – MP5 Serie (Standard V2)

Kompakte Präzisionskomponente | Optimiert für TM, CYMA & Echo1 MP5 | Maximale Air-Seal Integrität

Das Polarstar Jack™ Nozzle #2 ist die spezialisierte Komponente für die Integration der Jack-HPA-Engine in die populäre MP5-Serie. Da die MP5-Plattform (V2-basiert) eine andere Nozzle-Länge als Standard-M4-Modelle erfordert, wurde dieses Bauteil exakt nach Tokyo Marui Spezifikationen gefertigt. Es garantiert eine perfekte Abdichtung an der Hop-Up Schnittstelle und ist die Basis für ein extrem zuverlässiges CQB-Setup.

Technische Details & Performance:

  • MP5-Spezifische Kalibrierung (#2): Die Länge entspricht exakt dem Standard für MP5-Modelle von Tokyo Marui, CYMA und Echo1. Dies gewährleistet ein fehlerfreies Feeding und eine 100%ige Abdichtung im Hop-Up Bucking.
  • Optimiert für Single-Solenoid Systeme: Als integraler Bestandteil der Jack-Engine ermöglicht dieses Nozzle einen schnellen und effizienten Bewegungszyklus. Dies sorgt für ein extrem reaktionsschnelles Ansprechverhalten, ideal für schnelle Schussfolgen in CQB-Szenarien.
  • High-Performance Material: Gefertigt aus einem reibungsarmen Polymer-Verbundwerkstoff. Dies schont die Lippen Ihres Hop-Up Gummis und minimiert den mechanischen Widerstand während des Ladezyklus.
  • Laminarer Luftstrom: Die präzise interne Geometrie leitet die Luft ohne Turbulenzen hinter die BB, was die Präzision und die Konstanz der Mündungsgeschwindigkeit (FPS) maximiert.

Kompatibilität:

  • Engine: Ausschließlich kompatibel mit dem Polarstar Jack™ System.
  • Waffen-Plattformen (V2 Gearbox Spec):
    • Tokyo Marui: MP5 A4, A5, SD5, SD6 Serien.
    • CYMA: MP5 Serie (z. B. CM.041, CM.041SD).
    • Echo1: SOB Serie und andere MP5-Varianten.
    • JG (Jing Gong): Ebenfalls kompatibel mit den meisten JG MP5 Modellen.

Vorteile beim Jack-Umbau:

Die Umrüstung einer MP5 auf Polarstar Jack macht sie zur ultimativen CQB-Waffe: extrem leicht, leise und wartungsarm. Durch den Austausch des Standard-Nozzles gegen dieses Präzisionsbauteil eliminieren Sie die typischen Undichtigkeiten an der Hop-Up Unit. Das Resultat ist ein hocheffizientes System, das keine Energie durch "Air-Leaks" verschwendet und durch eine extrem konstante Performance überzeugt.

Technik-Tipp: MP5-Modelle haben oft bauartbedingte Toleranzen bei der Magazinhalterung. Wir empfehlen, bei der Installation des Nozzles #2 sicherzustellen, dass die Hop-Up Unit fest am Gehäuse anliegt, um die maximale Dichtleistung zu erzielen.

I Wanted to Like It
Style: SPF 50, Size: 1 count (Pack of 1)
I really wanted to like it because of the great reviews it gets with backpackers and generally with people that don't like "greasy hands syndrome" after applying sunscreen. But after using a stick I found that it's just not that good. The good: small, lightweight container. Not greasy. Good protection, I was in the sun all day hiking multiple days straight and only put on sunscreen twice per day and I didn't have any burning... and I burn easily. The bad: Value: the $12.53 sunscreen container only lasted about 8 days. And that was just my arms, neck, and half my face since I wore a shirt and long pants and a wide brim hat every day when hiking. I would expect this amount of sunscreen to last a lot longer than that on such a limited area. I'm not a big person either. Application, chafing: it's the opposite of greasy, almost chalky. You use the stick to apply to your skin in stripes, then you have to "blend it in" by rubbing with the backs of your hands so your palms don't get chalky. Since the stick is so dry this requires a fair amount of force and it chafes as you rub it around. When your skin a bit sandy it hurts. Application, crumbling: on a chilly but sunny morning, about 45 F, I applied sunscreen and small chunks of the stick crumbled off. I watched precious chunks of the already overpriced sunscreen drop to the ground. Residue: while it's not greasy, it's physical sunblock so it gives your skin the characteristic whitish sparkle. That's to be expected. But what I didn't foresee is it will rub off on anything your skin touches. My gear had white chalk-like marks (technically titania powder?) on my shirt collars, backpack straps, sunglasses, and a few other high-touch items. Overall I think it's a neat idea. I'm not overly disappointed with my purchase. But for $12.50 I expect sunscreen to be easier to apply and for the container to last longer than about 8 days. I can't burn $50/month in the summer months when a single container of chemical sunscreen will do the job. Pro tip: you can buy food-safe 3 oz TSA travel containers. Load one of those up with chemical sunscreen and you have something that beats this in every way except for the greasiness, which you can mitigate by picking a lower SPF sunscreen (the 30 SPF you wear is infinitely better than the 50 SPF you skip!).

Best sunscreen for kids
This is the only sunscreen my son can use. He has very sensitive skin, and can’t use a lot of other sunscreens. This covers great and is a little thicker so you know it’s staying on.

Like it but doesn’t rub in great
Happy with this sunscreen even though it’s hard to rub in. Keeps us protected from the sun and lasts us quite awhile!
