Top takeaways

  1. Sprinco's Extractor Springs are heat treated and cryogenically processed for durability, and can handle heat up to 750°F without performance degradation.
  2. The XP 5-Coil spring offers a heavier load than standard OEM springs, making additional D-Fender™ rings or CRANE Viton O-Rings unnecessary.
  3. While suitable for all 5.56 BBL lengths, the 5-Coil spring may be too strong for rifles with 18""+ barrels or bolts with tight tolerances, potentially damaging case rims.
