Spring SP 100 [Guarder]

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 …………………………………………………………………………

Cons:

None! This spring has exceeded all my expectations.

With this spring the Arcturus AK12 has a nice ~360 FPS. This spring has a fair price compared to it's good quality. It was easy to install and will work for a long time I guess.
I could suggest it especially for the Arcturus AK12 series.

I have tried few different manufacturers, CYMA 045C definitely likes this spring the most, it is giving me the most consistant fps (326-327) in combination with all compression upgrades and other mods. Also it is quite good with elimination of overcycling due to its lenght. Definitely good product.

Still the best spring in the market. Long lasting, strong and easy to calculate how the muzzle speed change. My AK12K by Acturus shoot around 370 FPS with this spring. I can't understand why to use stronger spring like this ...
