Will be fit for glock 23 Expert Answer

This is what you need for a parts rig by Dave, Verified Owner, September 4, 2025
Easy to install, keeps perfect zero, and allows excellent flexibility for PDW-type builds where you actually want the optic to be a little higher up. The (not included) charging handle makes it a complete no-brainer.
