Guarder SP110 Spring

The SP110 rating indicates the spring's power level, which is roughly equivalent to a 110-meter-per-second muzzle velocity with a standard .20g BB. It is designed to provide a moderate power increase, making it a popular choice for balancing field-legal velocity with internal component longevity.

The Guarder SP110 is designed for broad compatibility and fits most standard AEG gearbox versions, including V2, V3, V6, and V7. It is a universal-style spring, but you should verify your specific gearbox type before installation to ensure proper seating.

While the SP110 is a moderate upgrade, it is always best practice to ensure your existing piston, gears, and motor can handle the increased tension. If you are currently running stock plastic internal parts, upgrading to a metal-tooth piston and reinforced gears is recommended to prevent premature wear.

Linear springs provide a consistent rate of compression throughout the entire stroke, which often results in more predictable shot-to-shot consistency. This makes them ideal for players who prioritize accuracy and stable muzzle velocity over the slightly easier gearbox cycling sometimes offered by non-linear springs.

The black finish on the Guarder SP110 is a protective coating applied to the hardened steel alloy. It helps prevent oxidation and corrosion, ensuring the spring maintains its structural integrity and performance over time.
