657780264032 Sprinco’s Extractor Springs are made of chrome silicon wirestock that has been heat treated, stress relieved, and cryogenic processing post winding. The springs are also plated with re-micronized molybdenum disulfide formulation. ADVANTAGES: XP 5-Coil spring has a heavier spring load than OEM springs, thus negating the need for a D-Fender™ ring or adding CRANE Viton O-Rings Use 5-Coil spring with either black extractor spring insert OR CRANE Viton O-Rings, but not both Enhanced 4-Coil springs maintain an extended duty cycle load of a NEW Mil-Spec spring and is recommended for use in 18""+BBL lengths for those who retrieve their brass for reloading While the XP 5-Coil spring is totally reliable for all 5.56 BBL lengths, it can be aggressive on case rims in 18""+length BBL rifles, and may be too strong for some bolts with extremely tight bolt face tolerances Extreme duty cycles provided while maintaining performance specifications Unaffected by heat up to 750°F D-Fender™ rings are NOT recommended for use with our 5-Coil extractor springs. Dual spring XP .308 extractor spring sets may be used with or without CRANE O-rings. May be required for use in DPMS G2 Bolts for full-auto use. Plug & play - May easily be the only extractor springs needed for the life of your bolt!!

Description:

Upgrade your extractor performance with SPRINCO USA's innovative kits!

Sprinco’s Extractor Springs are crafted from premium chrome silicon wirestock that undergoes heat treatment, stress relief, and cryogenic processing after winding, ensuring durability and reliability. Each spring is plated with a re-micronized molybdenum disulfide formulation for enhanced performance.

Key Advantages:

  • XP 5-Coil Spring: Offers a heavier spring load compared to OEM springs, eliminating the need for a D-Fender™ ring or 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.
  • Extended Duty Cycle: Enhanced 4-Coil springs maintain a load equivalent to a NEW Mil-Spec spring, ideal for 18"+ BBL lengths, especially for those who retrieve brass for reloading.
  • Performance: The XP 5-Coil spring is reliable across all 5.56 BBL lengths, though it may be aggressive on case rims in 18"+ BBL rifles and could be too strong for bolts with extremely tight tolerances.
  • Extreme Duty Cycles: Designed to provide exceptional performance specifications while remaining unaffected by heat up to 750°F.
  • Compatibility Note: D-Fender™ rings are NOT recommended with our 5-Coil extractor springs.
  • Dual Spring Sets: XP .308 extractor spring sets can be used with or without CRANE O-rings, which may be necessary for full-auto use in DPMS G2 Bolts.
  • Easy Installation: Plug & play design makes these extractor springs potentially the only ones needed for the life of your bolt!


Top takeaways

  1. Sprinco’s Extractor Springs are made from heat-treated chrome silicon, cryogenically processed, and molybdenum disulfide plated for durability and performance.
  2. The XP 5-Coil spring provides a heavier load than OEM springs, eliminating the need for additional D-Fender™ rings or CRANE Viton O-Rings.
  3. Enhanced 4-Coil springs are recommended for 18" or longer barrels for those who reload, while the 5-Coil spring is reliable for all 5.56 barrel lengths but may be too strong for certain bolts.
