NON-LINER Main Spring MS150 SP

As the
mythical Prometheus has delivered fire to humanity and taught us basic technology,
so does Prometheus bring us modern technical solutions for our airsoft replicas.

Non-linear
coiling of the spring prevents its breaking and reduces the effect of
compression, thus extending the spring’s usability and the period of retaining
its stock technical parameters.

The
main spring is intended for tuning of electric replicas. The power drained from
installation of a main spring depends on how well sealed is a system, the type
of implemented cylinder as well as barrel length and its diameter.
