Red dot mounts for Glock 31

This collection contains red dot mounts for the Glock 31. The mount goes into the rear sight dovetail in place of the rear sight. You fit a red dot without milling and without permanent changes, and you can put the rear sight back at any time. We have mounts for the Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP, Docter and C-More RTS footprints, made by Angry Bear, EGW, Holosun, Outer Impact, Toni System and Zendl.

The Toni System frame mount installs on the bottom of the frame of the Glock gen 4, not on the slide. It takes the Trijicon RMR footprint, and the red dot stays still while the slide cycles.

Choose the mount by the footprint of your red dot and check that your model is named in the title. You find a full guide to these mounts, their footprints, materials and installation in Red dot mounts for Glock 17.
