- 04.05.2026 wrote:The Guarder SP110 AEG spring is a well-regarded upgrade part for players looking to fine-tune their airsoft replica’s power output. Designed for standard AEG gearboxes, it typically delivers around 104–110 m/s (approximately 340–360 FPS with 0.20 g BBs), depending on the overall internal setup of the rifle.
In terms of build quality, the spring is made from tempered silicon-chrome steel wire, which gives it strong durability and long-term resistance to fatigue. It maintains consistent performance even after extended use, which is one of the main reasons Guarder springs are popular among tech-oriented players.
During gameplay, the SP110 provides stable and predictable FPS output when paired with a well-sealed gearbox. It is often praised for its consistency compared to cheaper alternatives, making it easier to tune a replica without unexpected velocity fluctuations. However, actual performance still depends heavily on airseal, barrel setup, and gearbox efficiency.
Overall, the Guarder SP110 is a reliable mid-power spring that offers good balance between durability, consistency, and field-legal performance for most outdoor airsoft builds. -

These and consistent, the packaging is clear about the power level, and the price is good. -

Recommmend using this battery with 7.4v lipo at least, works greatly with 11.1v also. Also recommend it As replacement in mid tier quality replicas stock spring.
