IBS Complete Upper for Glock 43/43X
Zaffiri Precision Complete Uppers built on the IBS platform are designed around an integrated ported system that pairs the slide and barrel for proper alignment. Each assembly is built around a billet stainless steel slide finished in Black or FDE Cerakote and matched with an IBS barrel featuring Chunk Porting to create a cohesive, ported configuration. This system is designed to ensure proper alignment between slide ports and barrel porting while maintaining a clean, integrated setup.
All Zaffiri Precision complete slides are optics-ready and include a cover plate and mounting screws. Each slimline slide assembly is equipped with blacked out iron sights that provide a lower 1/3 co-witness with Holosun 507K, EPS Carry, and similar height optics.
