The FPS120 power spring is the ideal solution for players who want to boost the power and reliability of their airsoft replicas. Designed to deliver a comprehensive upgrade, this spring ensures constant power output, making it perfect for competitive airsoft scenarios where enhanced performance is key. With meticulous engineering, the FPS120 spring is compatible with replicas featuring barrels from 301 to 400 mm and gearboxes with type D cylinders, ensuring a perfect fit and optimized air group performance.

Manufactured using carbon steel that is pre-hardened and burnished, and further enhanced with silicon and chromium (in accordance with EN10270/2), this spring stands out for its durability and strength. Its variable pitch coils, both in the central area and at the ends, allow for tailored power modulation based on your replica’s configuration, ensuring consistent and reliable shots. A stabilization process, consisting of a thermal treatment at 400°C for 30 minutes, helps maintain the spring’s mechanical properties over time, making it an essential component for maximum performance.
