Dawson Precision Glock rear sights deliver the notch width and sight radius consistency that Production and CO competitors require. Fixed models cut to Dawson's exacting notch dimensions eliminate the visual ambiguity of generic aftermarket rears, while adjustable versions let you fine-tune elevation across power factors without swapping front sight height. All models are machined to standard Glock dovetail specs for direct installation. Fast same-day shipping on most orders at Shooters Connection.
