This Glock OEM 6.9mm polymer fixed rear sight is the genuine Glock factory part, with a white U-outline notch around the rear aperture. It drops into the standard Glock rear dovetail as a direct factory replacement for a worn, broken or missing rear sight on the Glock 20, 21, 29, 30, 36 and 37.

The white U-outline frames the front sight for a fast, simple sight picture, the same setup Glock ships from the factory. If you have changed sights and want to go back to stock, or need a spare for a duty or range pistol, this is the original part rather than a copy.

Features:

• Genuine Glock OEM polymer rear sight
• 6.9mm sight height
• White U-outline notch
• Standard Glock dovetail fit
• Fits Glock 20, 21, 29, 30, 36 and 37

This wide-body 6.9mm profile does not fit the slimline Glock 42, 43, 43X or 48, where it overhangs. Match the rear sight height to your front sight for a correct point of impact. Use a sight pusher or a rear sight tool to install it, center it in the dovetail, and confirm zero at the range before you carry the pistol.
