The Guarder SP140 is a high-performance power spring designed for DMR and long-range AEG builds requiring superior shot-to-shot consistency. Manufactured from oil-tempered steel wire, Guarder springs are widely recognized for their "anti-settling" characteristics, ensuring the spring retains its original tension and length even after a rigorous break-in period. The irregular pitch (non-linear) winding reduces the initial load on the motor and gears at the start of the compression cycle, improving trigger response while delivering maximum force at the point of release. This makes the SP140 an ideal choice for technicians seeking to maximize muzzle energy while minimizing mechanical wear on the gearbox drivetrain.

Technical Specifications:

  • Material Construction: Manufactured from high-tensile oil-tempered steel wire for maximum fatigue resistance and tension stability.
  • Spring Rate: Rated as an SP140, typically producing muzzle velocities between 450 and 480 FPS depending on the compression efficiency of the system.
  • Irregular Pitch Design: Features non-linear winding to facilitate an easier initial compression and reduce peak stress on the motor.
  • Settling Resistance: Precision heat-treated to ensure the spring maintains its power rating over thousands of cycles without significant FPS drop.
  • Surface Treatment: Finished with a professional black coating for superior corrosion resistance and reduced friction against internal components.
  • Compatibility: Designed for standard Tokyo Marui-spec AEG gearboxes (Version 2, 3, 6, etc.).
  • Compatibility Exceptions: Specifically not compatible with the Tokyo Marui NGRS (Next Gen Recoil Shock) series or the Tokyo Marui PSG-1.
  • Northmark Vault Recommendation: The SP140 is a high-tension spring; it is best paired with a high-torque motor and full steel-rack piston for optimal durability.
