Zaffiri Precision IBS Complete Upper 9mm Luger - Fits Glock 19 Gen 3 - FDE/Black Nitride - RMR Cut

The Zaffiri Precision Complete Upper IBS Slide is an aftermarket slide assembly for the Glock 19 Gen 3, chambered in 9mm Luger. It upgrades a factory frame with the Integrated Blowhole System ported slide design, an RMR-pattern optic cut, and a Black Nitride chunk-ported barrel.

The slide is CNC machined from a single billet of 17-4 stainless steel and finished in a durable Flat Dark Earth Cerakote. IBS porting channels propellant gases upward through the slide to reduce muzzle rise and help the pistol stay flat during rapid strings of fire. A precision-milled RMR optic cut accepts Trijicon RMR and compatible reflex optics without adapter plates, and blank co-witness iron sights are installed from the factory for use with or without an optic.

The included drop-in barrel is a 9mm Luger chunk-ported unit finished in Black Nitride, complementing the FDE slide and matching the IBS porting for a cohesive compensated package. Zaffiri Precision includes the complete upper parts kit needed for installation on a Glock 19 Gen 3 frame.
