Sprężyna SP 90 [Guarder]

Przy komoze hop up maxx4 czerwonej , na gumce 55-60* dobrze uszczelnionej replice z cnc daje 280fps i okolo 0.7j na kulkach 0.28 sprawdzona w boju jest ok. polecam jak ktos nie chce za mocnej do cqb ,

Sprężyna jak to sprężyna. Daje 0.99 J w replice z jako tako szczelnym układem, na kulkach 0.32. Moc mogła zaniżyć dłuższa lufa (410mm) i mocniej dokręcony hop up.

Guarderów niestety nie da się odróżnić na pierwszy rzut oka, więc trzeba pamiętać żeby je jakoś oznaczyć albo wkładać do odpowiednich fabrycznych opakowań przy zmianie sprężyny w celu dostosowania repliki do innego limitu.

Sprężyna w porządku, przeszła dobrze zabezpieczona. Jest trochę dłuższa od stockowej rk 05 Boyi, więc trzeba uważać przy jej wkładaniu.
Faktycznie zgodnie z opisem na stronie dużo zależy od części wewnętrznych, pomimo planowanej zmiany na okolice 330-350 fps finalnie wyszło ok 240fps, ale dzięki temu wykrylem duże nieszczelności układu, przede wszystkim dyszy :)
Teraz wszystko śmiga na okolicach 330.

Jeżeli zmieniasz sprężynę sprawdź przy okazji szczelność układu.

Polecam.

Dobra, sprawdzona podstawowa sprężyna do repliki m904g. Jak dotąd ani razu mnie nie zawiodła. Polecam na początek na rozgrywki CQB. Świetna alternatywa dla środkowych sprężyn. W moim DE kręci równo 1.1J przy kulkach .28

Sprężyna bardzo dobrze wykonana zapakowana była w odpowiednie opakowanie. Widać kilku stopniowe uzwojenie. Po zamontowaniu w replice M904G od DE daje nam 330fps także idealnie mieścimy się w limitach CQB. Polecam

I have installed this SP90 spring in several of my airsoft guns, especially the ones I use for CQB. Installation is very easy, particularly if the gun has a quick change spring system. It consistently hits right around 1J, which makes it perfect for indoor games. So far, I have mainly installed them in Double Eagle replicas.

Perfectly working, a good quality piece for overjoule gearboxes, this has a nice finish/coating.
I used it on a 1.35j gearbox and made it 0.83j, next time I'll try a 95 or a 100 of the same series.

I have used other brands springs before and there was a lot of variance that made it pretty much impossible to predict what any 1 spring was gonna do power wise, which was extremely annoying as it meant taking a replica apart lots of times to chrono different ones.
These and consistent, the packaging is clear about the power level, and the price is good.

Perfect as expected fast delivery highly recommended So good packaging and very nice customer service Amazing condition as expected and very happy to buy from taiwangun …………………………………………………………………………

Excellent Value and Service from taiwangun.com
The Spring SP 90 is reasonably priced for the quality and performance it offers, making it a worthwhile investment for any airsoft player. Additionally, I want to commend taiwangun.com for their exceptional service. My order was processed quickly, and the shipping was prompt. The product arrived in perfect condition, demonstrating their commitment to customer satisfaction.

Put this in my Arcturus AT-AK12K-PE and it now shoot at exactly 350 fps ,1.14J with 0.2g bbs (EU field legal)

Feels sturdy and shoots consistently. Never had any issues with it.

(Remember to have the compressed coils in the rear.)

Not much to say about this. Bought it so I would have a backup option in case I made my gun too powerful after messing with the gearbox following some upgrades.

From my inspection, it feels sturdy enough and can't see anyone having issues with this brand.

A good spring, good quality and works well. I got it paired with my UTR45 since it had a quick change spring mechanism. Handy thing to have if you want to play range in the morning and then maybe cqb in the afternoon.

Overall a good product, would recommend it to just have as a spare in your toolbox or something incase you get the feeling that you want to go cqb.
