The Universal (Optics) Mount for Glock revolutionizes the way you mount optics on your handgun. It has the lowest bore axis the industry which saves you the hassle and inconvenience of cutting your slide or having to purchase an aftermarket slide. The GUM is compatible with many of the most popular red dot optics to include: Burris Fast Fire II & III, Leupold Delta Point reflex sights, Docters II & III, EoTech MRDS, Trijicon RMR, Vortex Venom and Viper, and many more. The mount is secured to the side via the dove tail with 6 set screws which provides a steady and rugged mount that repeatedly holds zero.

Note: While installing, you may mark your slide when using this mount to properly secure the mount. Per the manufacturer, it is highly recommended that you have a gunsmith install the GUM and utilize the correct tools for installation.
