Description

Poseidon M140 ECO Spring

The brand Poseidon has appeared on the market with a range of tuning parts with a quality of workmanship rarely seen before. When selecting materials, Poseidon relies exclusively on high-quality components. The company also goes beyond familiar and tried-and-tested schemes in the manufacture of parts in classic configurations and obsolete designs and utilises innovative solutions to increase performance.

The M140 mainspring with irregular pitch, intended for electric replicas, was made of steel. The implementation of the M140 spring should allow a muzzle velocity of ~450 FPS depending on the materials used.
