SP130 AEG | Tune Up Spring | Guarder

SP130 AEG Tune Up Spring by Guarder – for your replica

This AEG spring determines the force with which the piston is driven in your gearbox. The SP130 (M130) spring generates a spring force of 260%, which translates to approximately 450-550 FPS with a 0.20g BB. You replace the spring when you want more power for outdoor skirmishes or when your current spring shows signs of fatigue. This upgrade does require modified internals that can handle the extra power.

Technical specifications

The Guarder SP130 is manufactured from high-quality spring steel with a black finish. The spring features linear compression and a standard AEG diameter that fits V2 and V3 gearboxes. The spiral design ensures consistent pressure during the compression cycle. The total length and coils are matched to the M130 specification.

Compatibility and application

This spring is suitable for AEG replicas with reinforced internals. For these power levels, we recommend a reinforced piston, bearing spring guide, and possibly a high-torque motor. Installation requires gearbox experience and correct adjustment of the angle of engagement. Always check local FPS limits before installing this spring.
