NON-LINER Main Spring MS135 SP

As the mythical Prometheus had 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 a tuning of
electric replicas. The power drained from the 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.
