Frequently Asked Questions

What mounting footprint does this sight use? Source data on this specific listing’s mounting footprint is inconsistent between the product title and the catalog attribute, so please verify the exact footprint or slide cut with us before ordering.

Why does Viridian use a green dot instead of red? The human eye is more sensitive to green wavelengths in daylight, so a green dot can appear crisper and easier to pick up quickly than a red dot of the same brightness.
