Prometheus Non-Liner MS150 Main Spring

Constructed from a steel main spring designed for ASG replicas, this spring features an irregular winding pattern that minimizes strain on the gearbox while delivering high performance. This design helps to prevent breakage, reduces the risk of spring deformation, and significantly extends both its lifespan and the period during which its technical specifications are maintained.

The power output achieved after installing the spring varies based on system tightness, the type of cylinder implemented, as well as barrel length and diameter. Designed specifically for integration into electric airsoft replicas.
