Tokyo Marui Micro Pro Sight

The Tokyo Marui Micro Pro Sight is made to fit the G-series but also fits any 20mm rail system.

The screws on the back, top and right allow the user to adjust the dot horizontally and vertically. (Windage & Elevation). The brightness of the dot can be set to Low and High and, as one of the few sights in this format, the sight can also be manually switched off.

If you want to attach this sight to a Glock model, you will need a specific mount for this. This sight does not come with a pistol mount for Glock but only with a picatinny mount.
You can find the mount here!
