Spring SS, 63mm, AEG, SR25, SVD, AirsoftGuns

Spring SS, 63mm, AEG, SR25, SVD, AirsoftGuns. SuperSpring (SS) length 63 mm is mainly for using in most of AEG guns with standard length of piston (e.g. M4/M16, AK, G36, M14, MP5 etc.) and you can use it in guns with longer piston too (e.g. AEG SR25, spring operated SVD Dragunov etc.). Upgrade part from series AirsoftGuns Custom Parts. Spring is made from the highest quality Japanese spring wire VDSiCr for direct requests of service technicians from AirsoftGuns. We took advantage of our many years experiences with upgrade of airsoft guns. We used knowledge gained during work on tens of thousands of service orders. We have created a new product line named AirsoftGuns Custom Parts, where you can find the best parts for airsoft guns upgrade.

SuperSpring (SS) is practically the hardest possible version of airsoft spring, which is in dimension for mentioned gun model. To achieve greater flexibility and correct returning back to start position we don't use progression winding. Complete spring preload (spaces between each eyes) is set to lowest possible exceed value of the Tau. It determines quality of springs - mainly stability and flexibility for long time. With extreme high value of Tau and rapid weakening/squeezing airsoft springs we unfortunately meet every day during airsoft guns upgrade.

If you want a maximum power of your gun, you have met with many variations of airsoft springs. Unfortunately, not all have the ideal length, hardness or durability for certain type of gun, and therefore can not be used their full potential. Our tuned springs from high quality wire are offered in different lengths (after full pressing), so everyone can choose the most suitable option. Someone uses long spring with the largest number of working eyes without axial bearings in the piston and spring guide, another has QSC rotary spring guide and will need shorter spring.

length after full pressing: 63 mm
wire diameter: 1.90 mm
outer diameter: 14 mm
material: VDSiCr
number of turns: 33

To achieve the same performance, it is necessary to use quality upgrade parts and is necessary correct and professional installation too. If you're interested in quality upgrade of your airsoft guns, you can contact directly our service department.

If you want to know more how is it with power of springs, we recommend an interesting article about real hardness of airsoft springs and how to mesure them. There you can learn that it is not good to believe label on the packaging of the spring, because the absence of common standards allows manufacturers to mark the spring hardness quite different. It is important to say that the measurement of hardness with our measuring rod can be used only with springs which have the total number of turns about 29 - 32. If is spring out of interval the measuring will be incorrect. It is better to use "weight" method of full pressed spring.
