NON-LINER MS70-85 SP Main spring

Just as the mythical Prometheus brought fire to mankind and taught us the basics of technology, Prometheus brings us modern technical solutions for our airsoft replicas.

Non-linear coiling of the spring prevents it from breaking and reduces the effect of compression, which extends the usability of the spring and the time it retains its technical parameters.

The mainspring is intended for tuning electrical replicas. The power that is extracted from the installation of the main spring depends on how well the system is sealed, on the type of cylinder installed and on the barrel length and its diameter.
