Glock, Factory Fixed Rear Sight 6.1mm Steel Matte

The Glock OEM Fixed Rear Sight 6.1mm steel sight brings a rugged, service-grade option to shooters who want reliable sight picture on full-size and compact Glock pistols; its matte steel construction and white contrast insert deliver rapid sight acquisition for range work, duty applications, and competition stages where speed and repeatability matter. Designed as the factory steel rear sight, this 6.1mm notch fits all Glock models except the G42 and G43 and is the standard rear sight for the G17L, so installation and alignment are straightforward for those swapping out aftermarket sets or replacing a worn OEM unit. The fixed rear design provides a solid reference plane with minimal movement under recoil, while the high-visibility white insert enhances target focus in low-light drill work or during quick follow-up shots at close to medium distances. Shooters who run Glock OEM sights appreciate the durable finish and dimensional match to factory front sights for co-witnessing within optic setups and for consistent sight radius retention. This sight is a no-frills, durable choice for operators, competitive shooters, and range enthusiasts seeking Glock OEM fit, consistent performance, and fast sight acquisition.
