PIANO Wire Steel Spring for AEG - M140

AA PIANO Wire Steel Spring for AEG - M140 Action Army's PIANO spring delivers consistent performance through high-grade spring steel construction and progressive coil design. The graduated winding reduces mechanical stress on gears and motor while maintaining stable output around 140 m/s. Factory pre-tensioning ensures reliable performance from initial cycles without the degradation common in lower-grade springs. Engineered to withstand sustained high-rate-of-fire use without losing tension or breaking, this upgrade component is essential for long-term gearbox reliability. Compatible with most standard AEG gearboxes. Install with the compressed coil section toward the spring guide.
