Expo Arms AR-15 Extractor Spring Enhancement Kit

Upgrade your AR-15 with the Expo Arms AR-15 Extractor Spring Enhancement Kit, featuring a replacement spring and O-ring that sits inside the bolt extractor and provides the tension needed to positively grip the cartridge rim through every extraction cycle.

• Includes spring, O-ring, and buffer

The extractor spring is one of the most critical small components in the AR-15 bolt group. It sits inside the extractor and pushes the extractor claw outward with enough tension to snap over and grip the cartridge rim during chambering, hold the case firmly during firing, and pull it clear of the chamber during extraction. A weak or fatigued extractor spring is a leading cause of failure-to-extract and failure-to-eject malfunctions, particularly under sustained fire, cold temperatures, or with dirty chambers where additional extraction force is required. Replacing the extractor spring periodically — or at the first sign of extraction inconsistencies — is a straightforward preventive maintenance step that keeps your AR-15 running reliably. The Expo Arms extractor spring is manufactured to mil-spec dimensions for a direct drop-in fit in standard AR-15 bolts. Keeping a spare in your range bag or maintenance kit enables expedient field repair without taking the rifle out of service.

Backed by Expo Arms' commitment to quality mil-spec components. Expo Arms manufactures AR-15 parts and accessories to mil-spec standards.
