Top takeaways

  1. Sprinco's Extractor Springs are heat treated and cryo processed for durability, can handle heat up to 750°F, and are plated with molybdenum disulfide for enhanced performance.
  2. The 5-Coil spring is suitable for all 5.56 BBL lengths but may be too strong for 18"+ BBL rifles or bolts with tight tolerances, while the 4-Coil is recommended for extended duty in 18"+ BBLs.
  3. These springs are designed for longevity, potentially lasting the lifetime of the bolt, and the .308 extractor springs can be used with or without CRANE O-rings.
