Warning

• Some manufacturers’ springs are significantly overrated (e.g., an M130 spring may perform like M140–150), which may exceed the declared gearbox strength. We recommend using only the included Specna Arms springs. With other brands, an M120 spring is generally the safe choice.
• When installing springs with progressive (irregular) coils, ensure the tighter coil end is placed on the spring guide facing outward from the gearbox.
• Never store the rifle with a connected battery.
• Never store the rifle with pre-cocking enabled. Always release the piston forward before storage to avoid spring damage.
