NON-LINER Main Spring MS135 SP

NON-LINER main spring MS135 SP

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.

The non-linear winding of the spring prevents it from breaking and reduces the effect of compression, which extends the usability of the spring and the duration of maintaining its technical parameters.

The main spring is designed for tuning electric replicas. The performance obtained from the installation of the mainspring depends on how well the system is sealed, on the type of cylinder used and on the length of the barrel and its diameter.
