Zaffiri Precision G19 Gen 3 Complete Upper Slide 9mm Luger IBS RMR-Cut FDE with Gold TiN Barrel

Upgrade your Glock 19 Gen 3 with the Zaffiri Precision CU-G19G3 Complete Upper Slide, a drop-in slide assembly from the manufacturer's Integrated Blowhole System (IBS) line. Machined from stainless steel and coated in Flat Dark Earth, this complete upper is chambered in 9mm Luger and ready to mount on a Gen 3 frame.

The compensated IBS platform routes propellant gas through precision ports in the slide to reduce muzzle climb and help the shooter stay on target through faster strings of fire. The matched Gold TiN-finished barrel is fitted to the slide at the factory for a consistent lockup and reliable cycling.

An RMR-pattern optic cut is milled into the top of the slide for direct mounting of Trijicon RMR and other compatible reflex optics. The slide ships with blank co-witness sights installed so the builder can pair iron sights with their red dot of choice, or run the optic alone. Whether you are setting up a compensated carry gun, a competition pistol, or refreshing a worn Gen 3 slide, this Zaffiri Precision complete upper is built to drop on and go.
