DT Snap Fit ARD - Holosun 407C/507C

This is intended for rifle use, like the red dot piggy backed on a scope. Durability is not guaranteed on a pistol with heavy holster usage.

This DOES NOT work on older models with the vertical buttons. Must be the newer design (as pictured) with the brightness adjustment buttons on the bottom. It is not designed for the old style and will break upon installation.

This Anti-Reflection Device (ARD) is designed for Holosun 407C and 507C model red dots. It securely snaps into the side dimples of the optic, providing a tight and reliable fit. There are additional options for an occluded version or a full cover, depending on your needs.

The ARD maintains clear visibility through the optic. While you may notice it if you’re focusing directly on it, it remains unobtrusive when your focus is on the target, as it should be. It effectively reduces glare from the sun and artificial lights, making it useful in both daytime and nighttime shooting.

For handgun users, the ARD includes a small viewing window at the base of the honeycomb mesh, allowing for unobstructed co-witnessing with low-profile iron sights.

Red dot not included.
