Top takeaways

  1. Sprinco USA's Extractor Springs are heat treated, stress relieved, and cryogenically processed for durability, with a molybdenum disulfide coating for performance.
  2. The 5-Coil spring is ideal for all 5.56 barrel lengths but may be too strong for 18"+ barrels or bolts with very tight tolerances, while the 4-Coil is recommended for longer barrels and brass reloading.
  3. These extractor springs can withstand temperatures up to 750°F and are designed to be the only springs needed for the life of your bolt, with no need for D-Fender™ rings when using the 5-Coil version.
