SP100 Spring for Tokyo Marui EVOLT AEG GUARDER

The Guarder SP100 spring for the Tokyo Marui EVOLT AEG is a replacement or upgrade part designed specifically for standard V2 and V3 gearboxes compatible with the EVOLT platform. Its key distinguishing feature is its irregular pitch, a design that reduces mechanical resistance at the beginning of the piston's stroke and concentrates maximum power at the end of the stroke, resulting in a smoother and more controlled cycle.

Made of silicon-chromium (Si-Cr) alloy steel and heat-treated via oil quenching, this spring retains its mechanical properties over time, even after thousands of cycles. Its surface treatment minimizes friction against the piston's inner walls, contributing to the assembly's longevity.

This spring is a reliable upgrade to stabilize the long-term performance of a Tokyo Marui EVOLT.
