The American Defense AD-AEMS is a quick-detach mount designed specifically for the Holosun AEMS red dot platform — this version at 1.93 in height, the popular raised height for a more upright, head-up shooting position and better use with plate carriers and helmets. ADM's patented Auto Lock QD lever attaches and removes the optic fast with repeatable zero, and self-adjusts to in-spec and out-of-spec Picatinny rails without tools.
Machined from 6061-T6 aluminium with a Type III Mil-Spec hardcoat finish. Made in the USA.
Height: 1.93 in — also available in Absolute Co-Witness, Lower 1/3 Co-Witness and 2.33 in Night Vision.
