Prometheus Non-linear MS135 spring - CRIMSON

Prometheus' high-quality M135 tuning spring for all electric weapons (not PSG-1). The spring gives a 0.20g bullet at about 135 m/s, about 1.8 J. Non-linear wire density improves performance and provides a smooth output.

Prometheus' new springs are color-coded to make it easier to change springs quickly. Please note that the final power output of a spring depends not only on the spring itself but also on other components, the gun and the bullet used. The best way to get the power you want is to test several different spring options.
