NON-LINER
Main Spring MS120 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.
