The American Defense AD-TR-LW QD Mount is a lightweight quick-detach mount for red dots on the Leupold DeltaPoint Pro footprint — including the DeltaPoint Pro, EOTech EFLX and Vortex Defender / Defender ST — this version at lower 1/3 co-witness height, placing the dot slightly above AR-height iron sights for a less cluttered window. ADM’s patented Auto Lock QD lever attaches and removes the optic fast with repeatable return-to-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 anodised finish. Made in the USA.
Height: Lower 1/3 Co-Witness — also available in Absolute Co-Witness.
