The American Defense AD-RMR-LW QD Mount is a lightweight quick-detach mount for the Trijicon RMR, SRO and red dots sharing the RMR mounting footprint — this version at a tall 1.93in height for a heads-up shooting position and stacked or laser-equipped setups. 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 hardcoat anodised finish. Made in the USA.
Height: 1.93in Height — also available in Absolute Co-Witness, Low, Low (Right-Hand Lever).

Frequently Asked Questions
Which optics fit?
Optics using the Trijicon RMR mounting footprint — e.g. RMR, SRO and similar red dots.
Why a 1.93in height?
The taller centreline supports a heads-up stance and clears folding irons, lasers and night-vision setups.
Does it return to zero?
Yes — the Auto Lock QD lever gives repeatable return-to-zero.
