The XP 5-coil XP Bolt Extractor CS Spring, 3-pack, is a precision replacement spring engineered for AR-platform rifles and tactical carbines where reliable case extraction is mission-critical. Designed by Sprinco USA—a manufacturer trusted across law enforcement and military armories—this bolt extractor spring assembly directly addresses extractor wear and degraded performance that accumulates through thousands of rounds. Whether you're running duty carbines, precision rifles, or high-round-count training platforms, a compromised extractor spring increases the risk of double-feeds, extraction failures, and jams at the worst possible moment.
This 3-pack offers three replacement springs engineered with Sprinco's proprietary XP coil geometry—a design that provides consistent spring rate and tension across the full range of chamber pressures and cycling speeds. The CS (Carbine Spring) variant is calibrated for standard AR bolt extractors and delivers reliable claw engagement with both brass and steel-cased ammunition. The 5-coil configuration balances durability and responsiveness, preventing the spring fatigue and loss of tension that plague lower-quality aftermarket springs. Unlike oversized or undersized springs that can cause extraction stutters or create excessive carrier wear, the XP 5-coil maintains factory-specification clearances and function.
Operators maintaining multiple rifles or running high-volume training and qualification cycles will appreciate the convenience and cost savings of a three-spring kit. Installation requires only field-stripping the bolt carrier group—no gunsmithing or specialized tools needed. This spring assembly is compatible with all mil-spec AR-15 and AR-10 bolt extractors and is ideal for preventive maintenance on rifles approaching 5,000–10,000+ rounds, or as an immediate fix when extraction reliability has begun to degrade. LEOs, military armorers, and competitive shooters rely on Sprinco springs to restore and maintain extraction consistency.
