NON-LINER Main Spring MS170 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.
