Warnings

• Some manufacturers’ springs are overrated (e.g., M130 may equal M140–150), potentially exceeding gearbox durability. Use only Specna Arms springs included. With other brands, M120 strength is recommended to prevent damage.
• When using springs with progressive (irregular) winding, ensure the tighter coil end is seated on the spring guide facing outward from the gearbox.
• Never store the rifle with the battery connected.
• Never store the rifle with pre-cocking enabled. Always release the piston before storage to avoid spring damage.
