ZAFFIRI ZPS.B.43.BLK.CU ZPS.B G43 UPPER 43BCPBN

The Zaffiri Precision ZPS.B G43 Upper Receiver in Black is a precision-machined replacement upper assembly engineered for Glock G43 platform pistols. This component represents a direct upgrade path for shooters seeking enhanced accuracy and durability beyond factory specifications, combining tight tolerances with rigorous quality control to deliver consistent performance across training, duty, and competitive applications.

Built to exacting tolerances, the ZPS.B upper integrates seamlessly with standard G43 lower receivers and fire control groups, maintaining full mechanical compatibility while improving slide cycling reliability and shot-to-shot consistency. At 1.08 lbs and compact dimensions (10 inches in length), the upper maintains the G43's concealable profile—critical for CCW, plainclothes duty, and compact carry roles. The black finish provides corrosion resistance suitable for varied environments, from humid coastal operations to urban patrol settings where salt spray or moisture exposure presents a maintenance challenge.

This upper assembly serves operators and serious shooters who demand reliability from a subcompact platform without compromise. Whether deployed for backup duty, off-duty carry by law enforcement, or precision-focused recreational shooting, the ZPS.B addresses the G43 shooter seeking measurable improvements in accuracy and durability. The component-level upgrade approach allows piecemeal customization, enabling shooters to enhance their platform without full-pistol replacement or extensive gunsmithing.

Zaffiri Precision focuses on precision-machined components for popular compact and subcompact platforms. The ZPS.B line represents the brand's commitment to tight tolerances and repeatability, positioning these uppers as a viable alternative to factory components for shooters willing to invest in aftermarket precision engineering for their carry or duty pistol.
