ZAFFIRI 17.5.UPK UPPER PARTS KIT GLK 17/34 G5

The Zaffiri Precision 17.5.UPK Upper Parts Kit for Glock 17 and 34 G5 delivers precision-engineered components designed for shooters who demand reliability and performance from their duty or competition platform. Built for law enforcement, military personnel, and serious civilian shooters, this upper parts kit addresses the need for quality replacement components and upgrades that maintain factory standards while offering improved consistency. Zaffiri Precision has earned a reputation among tactical professionals for manufacturing components that meet or exceed OEM specifications without compromise.

This upper parts kit is engineered to work seamlessly with Glock Gen 5 platforms, specifically the full-size Glock 17 and long-slide Glock 34 models. The kit includes critical upper assembly components—barrel, slide, firing pin, and associated parts—manufactured to exacting tolerances that ensure optimal feeding, extraction, and reliability across all ammunition types. Zaffiri precision machining and quality control mean you get consistent round-to-round performance, reduced malfunctions, and extended component service life compared to standard factory parts or lower-tier alternatives.

This kit is ideal for armorer-level maintenance, rebuild projects, or shooters upgrading worn components on duty weapons or match rifles. Installation requires basic gunsmith knowledge and proper tools; professional installation is recommended if you lack experience with Glock platform assembly. The compact package (3.7 x 0.9 x 4.3 inches) ships efficiently and integrates directly with your existing lower frame, making this a straightforward upgrade path for users already committed to the Glock platform.
