Warnings

• Springs from some manufacturers are significantly overpowered (e.g., an M130 may perform like an M140–150), which may exceed the declared gearbox durability. We recommend using only the included Specna Arms springs. If using springs from other brands, choose M120-class springs to avoid potential damage.
• If installing a spring with progressive (irregular) winding, make sure the tighter coil end faces outward toward the spring guide.
• Never store the rifle with the battery connected.
• Never store the rifle with the piston pre-cocked (pre-cocking mode active). Always release the piston before storage to avoid spring damage.
