The ZF-5 9mm Extractor Spring is a great part to keep on hand for future maintenance. As the most commonly replaced wear component, a new extractor spring should be installed when the end user notices less consistent extraction and ejection.
Compatible with ZF-5, MP5, SP5, MP5K, SP-89, SP5K, MP5SD and other 9mm roller-delayed blowback firearms.
