IBS Complete Upper for Glock 19 Gen 5
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 assembly is equipped with blacked out iron sights that provide a lower 1/3 co-witness with RMR, Holosun 507C, and similar height optics.
