SPRINCO USA UPGRADE KIT-4-COIL EXTRACTOR SPRING, INSERT, O-RING

Notify on availability

Description:

Upgrade your extractor performance with Sprinco's advanced spring kits!

Sprinco’s Extractor Springs are crafted from high-quality chrome silicon wirestock that undergoes heat treatment, stress relief, and cryogenic processing post winding. These springs are coated with a re-micronized molybdenum disulfide formulation for enhanced durability.

Advantages of Sprinco Extractor Springs:

  • XP 5-Coil Spring: Offers a heavier spring load than OEM springs, eliminating the need for a D-Fender™ ring or additional CRANE Viton O-Rings.
  • Compatibility: Use the 5-Coil spring with either a black extractor spring insert or CRANE Viton O-Rings, but not both simultaneously.
  • Enhanced 4-Coil Springs: Maintain an extended duty cycle load equivalent to a new Mil-Spec spring, ideal for 18" or longer barrel lengths, perfect for those who retrieve brass for reloading.
  • Reliability: The XP 5-Coil spring is reliable for all 5.56 barrel lengths but may be aggressive on case rims in 18" or longer barrel rifles, and could be too strong for bolts with extremely tight tolerances.
  • Extreme Duty Cycles: These springs provide exceptional durability while maintaining performance specifications.
  • Heat Resistance: Unaffected by heat up to 750°F.
  • D-Fender™ Rings: Not recommended for use with our 5-Coil extractor springs.
  • Dual Spring XP .308 Extractor Spring Sets: Can be used with or without CRANE O-rings, and may be necessary for use in DPMS G2 bolts for full-auto applications.
  • Plug & Play: May be the only extractor springs needed for the life of your bolt!


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.
