Trijicon RMR ARD

The Trijicon RMR ARD is a simple snap in Anti-Reflection Device that can be installed in seconds with no tools or parts needed. In the pictures, I am using Polymaker PLA Pro FDE.

The downloaded files include STL and STEP file formats, as well as the parameterized OpenSCAD code used to generate both. This is so you can easily customize the following parameters for the hexagonal geometry:

window_depth = 14;
inner_diameter = 7;
hex_thickness = 0.5;

All units are in millimeters.
