PIANO Wire Steel Spring for AEG - M120
AA PIANO Wire Steel Spring for AEG - M120 Action Army's PIANO spring delivers consistent performance through high-grade spring steel construction and progressive coil design. The graduated winding pattern reduces stress on gears and motor while maintaining stable output around 120 m/s. Factory pre-tensioning ensures reliable performance from day one, resisting tension loss and fatigue that plague lower-quality springsāeven under sustained high-rate-of-fire use. The compressed end with tighter coils installs onto the spring guide. Compatible with most standard AEG gearboxes (V2, V3, and variants; excludes V2.5, L85, PSG-1, and proprietary designs). Engineered for durability and precision in demanding tactical scenarios.
