Upgrade your firearm's reliability with the AR .308 INNER EXTRACTOR SPRING from SPRINCO USA!
The AR .308 INNER EXTRACTOR SPRING, specifically designed by SPRINCO USA, offers numerous advantages for firearm enthusiasts looking to enhance their shooting experience.
Key Features:
- Heavier Spring Load: The XP 5-Coil spring boasts a heavier spring load compared to OEM springs, eliminating the need for a D-Fender™ ring or additional CRANE Viton O-Rings.
- Versatile Compatibility: Use the 5-Coil spring with either a black extractor spring insert or CRANE Viton O-Rings, but not both at the same time.
- Enhanced Durability: The enhanced 4-Coil springs maintain a duty cycle load comparable to a new Mil-Spec spring, making them ideal for 18”+ barrel lengths, especially for those who collect brass for reloading.
- Reliable Performance: While the XP 5-Coil spring is dependable for all 5.56 barrel lengths, please note it may be too aggressive on case rims for 18”+ length barrel rifles and could be overly strong for bolts with very tight bolt face tolerances.
- Extreme Duty Cycles: These springs provide extreme duty cycles while maintaining performance specifications, ensuring reliability under various conditions.
- Heat Resistance: Unaffected by heat up to 750°F, making them suitable for high-performance applications.
- Usage Recommendations: D-Fender™ rings are NOT recommended for use with our 5-Coil extractor springs. Dual spring XP .308 extractor spring sets can be utilized with or without CRANE O-rings, and may be necessary for DPMS G2 Bolts during full-auto use.
- Easy Installation: Plug & play design means these may be the only extractor springs you'll need for the life of your bolt!
