Top takeaways

  1. Sprinco's Extractor Springs are made from heat treated, stress relieved, and cryogenically processed chrome silicon wirestock, and are plated with molybdenum disulfide for enhanced performance.
  2. The 5-Coil spring offers a heavier load than OEM springs, eliminating the need for additional rings, and is reliable for all 5.56 barrel lengths, though it may be too strong for certain bolts.
  3. The 4-Coil springs are designed for extended duty cycles and are recommended for barrels over 18 inches, especially for those who reload their brass.
