Description

Reliable and preiserte spring from Element. The nominal value of the spring strength quantifies the expected value in m/s (metres per second) with 0.20g heavy ammunition and can be multiplied by a factor of 3.28 to achieve the value in fps.

The nominal value given is only a guide value, the effective firing force depends on the skills of the tuner and the seal of the system. When installed correctly, the effective value usually deviates less than 10% from the nominal value. Experience shows that in most cases the effective value is higher than the nominal value, therefore in case of doubt always tend towards the next weaker spring. In order to achieve the desired muzzle velocity as optimally as possible, it is often necessary to try out various components and combinations (springs, piston head, cylinder head, etc.). For systems with a particularly good seal (e.g. KWA G2X), massively lower nominal values must be selected.
In order to prevent the spring from breaking, at least one of the two supports (piston head or spring guide) should be mounted on ball bearings. We advise against tuning as a matter of principle, conversion work may only be carried out by expert users with the appropriate experience and technical skills and knowledge. Modification work usually reduces the reliability of the rifle and voids the warranty. We ask for your understanding that we cannot carry out any conversion work and cannot offer any help in the event of unsuccessful tuning. We also ask you to note that it is not sufficient to replace only one component in a tuning. All components must harmonise with each other to achieve the desired performance and to prevent defects.
