Top takeaways

  1. Sprinco USA's XP 5-Coil extractor spring is stronger than OEM springs, eliminating the need for additional modifications like a D-Fender™ ring or CRANE Viton O-Rings.
  2. The enhanced 4-Coil springs are ideal for 18" or longer barrels, maintaining the load of a new Mil-Spec spring, while the 5-Coil version is suitable for all 5.56 barrel lengths but may be too strong for some bolts.
  3. These extractor springs can withstand temperatures up to 750°F, are designed for extreme duty cycles, and may be the only extractor springs needed for the lifetime of a bolt.
