Adjustable Rear Sight for Glock 17 19 20 21 22 23 - TPU Series – Twin Dot - Precision Sights PSI
Adjustable rear sight for the Glock 17, 19, 20, 21, 22, 23.
Designed to fit into your standard factory dovetail without the need to change factory front sights and the need for a full armorer's tool box. These low profile sights provide a longer sight radius and is complemented by positive click adjustments for windage and elevation. CNC machined from steel for maximum strength. By replacing the factory rear sight with a TPU Series sight, micrometric adjustable for windage and elevation with hardened click screws, you will convert your semi-auto into a modern firearm ready for target and practical shooting. Will not work on Novak dovetails. Will not work on Glock Gen4 without gunsmithing.
Dovetail Width: .258
Sight Height: .268
