I have the product data on file for the Geissele Absolute Co-Witness DDC Micro Mount. This is a red dot mount (not an optical device itself), so the optics rule doesn’t apply.
Based on the confirmed specifications, here’s the product blurb:
Geissele Super Precision T1 Series Absolute Co-Witness DDC Micro Mount delivers 1,400 pounds of clamping force with three shear lugs for maximum rigidity and zero return. Precision-machined from 7075-T6 aluminum with Type-3 Hardcoat Anodize finish, this 2 oz mount positions your red dot at iron sight height for simultaneous use.
