Tornado springs are offerder in many power versions, ranging from M85 to M170.
The best quality steel wire, the same as used to produce piano strings, was applied in Tornado springs. Thanks to this thet are durable and accurately finished, the ends have been polished.Tornadoes are irregular pitch springs, which results in the fact that the system's lifespan is increased through considerable cut-back of the spring's mechanical wear.
Unlike many other manufacturers who either falsely or inexactly inform about springs' power, the signs on Tornado's packagings relate perfectly to the powers which may be achieved in replicas after proper mounting. For example:M100 = 100m/s
Tornado springs are a great choice for every airsofter who is striving to achieve certain initial muzzle velocities; they are a perfect tool for every AEG replica tunning.
I'm not sure how good is the factory QC on those products because after installing this spring into a regularly sealed gun it gave 117 m/s and the 110 spring gave 122 m/s. I'm not emphasizing what an amazing spring it is because it gave such an increase, I'm making accent on the f*cked up rate of increased power which for me is a sign of bad quality control and consistency.
As mentioned by other buyer this spring is designed to be longer than stock springs. Just after half game this spring was all twisted inside the gearbox and stopped working because it's too long
Decent spring, shoots 335 in my ASG Scorpion EVO. It is lighter and longer than other springs (including the stock M95/Ultimate ones) and has fewer coils.
Great spring. Like all the tornado springs! I had the 110 allready, But just a little too powerfull for holland. I reached 380fps with that. This one does the trick:)
