This upper parts kit provides all the small components needed to complete a Glock 17 Gen 4 slide assembly. It's designed for builders assembling custom slides or replacing worn internal parts in an existing slide. The kit includes the firing pin, firing pin safety, extractor assembly, and spring-loaded bearing—everything required for the upper to function properly.
