The American Defense AD-AEMS is a quick-detach replacement mount for the Holosun AEMS red dot, set at absolute co-witness height. It is precision machined from 6061-T6 aluminum and finished in hard-coat Type III mil-spec anodize.

The patented QD Auto Lock lever adapts to both in-spec and out-of-spec Picatinny rails, so the mount clamps fully without fine-tuning. Adjust lever tension with your finger or a flat-blade screwdriver; no proprietary tools are needed. The lever can be set to lock toward the front or the rear to suit your rail layout and handedness.

Features:

• Fits the Holosun AEMS red dot
• Absolute co-witness height
• Patented QD Auto Lock lever
• Accommodates in-spec and out-of-spec Picatinny rails
• Tension adjusts by hand or with a flat-blade screwdriver

Mount and check: Confirm the mount seats squarely on the rail before locking the lever, then check zero after the first removal and reinstallation to confirm return-to-zero on your rifle.
