American Defense AD-AEMS High QD Mount (1.93", Standard Lever)

The American Defense AD-AEMS-H-STD is the black standard-lever mount that places a Holosun AEMS at a 1.93-inch optical centerline. Its Auto Lock QD lever adjusts to in-spec and out-of-spec rails without a proprietary tool and can be configured to lock toward the front or rear.

The mount is machined from 6061-T6 aluminum and finished with Type III hardcoat anodizing. American Defense also sells separate absolute co-witness, lower-third, and 2.33-inch night-vision-height bases, plus tactical and titanium lever configurations. Those choices have their own part numbers and weights.
