Sprinco Buffer & Enhanced 4-Coil Bolt Extractor Spring Kit

The Sprinco USA Spring Kit (Sprinco part no. 25409) bundles a Sprinco buffer spring with an enhanced 4-coil bolt extractor spring in one purchase. The buffer spring drives the bolt carrier group back into battery, while the enhanced extractor spring adds tension behind the extractor claw for firmer case-rim contact than a stock-rate spring.

Key Specifications

• Sprinco buffer spring returns the bolt carrier group to battery after each cycle.
• enhanced 4-coil extractor spring adds tension behind the extractor claw beyond a stock-rate spring.
• sold as a two-part kit addressing both springs in a single purchase.
