The American Defense AD-RMR-LW QD Red Dot Mount for Trijicon RMR, Absolute Co-Witness is an American Defense Mfg. lightweight quick-detach mount for optics using the Trijicon RMR footprint, at absolute co-witness height. It clamps to a Picatinny rail with ADM's patented Auto Lock quick-detach lever, which self-adjusts to in-spec and out-of-spec Picatinny rails without tools and returns to zero when refitted.
How It Compares
This is the RMR-footprint mount, so it takes the Trijicon RMR Type 2, the Trijicon SRO and the Trijicon RMR HD, along with other red dots cut to the same pattern. The same mount is available as AD-RMR-LW at 1.93in height, AD-RMR-LW at low, AD-RMR-LW at low right-hand lever. For a Trijicon MRO take the AD-MRO-LW mount; for a Holosun 509T the AD-509T mount; for a Leupold DeltaPoint Pro footprint the AD-TR-LW mount — the AD-TR is a DeltaPoint Pro pattern despite the name, not a Trijicon one.

Frequently Asked Questions
Which optics fit this mount?
Optics cut to the Trijicon RMR mounting footprint, which includes the Trijicon RMR, the Trijicon SRO and other red dots sharing that pattern. It is not cut for the Trijicon MRO, Holosun 509T or Leupold DeltaPoint Pro footprints.
What height does this mount give?
This version is absolute co-witness, which sits the dot in line with AR-height iron sights, so irons and dot align through the same window.
Does this mount return to zero after removal?
Yes. It uses American Defense Mfg.'s patented Auto Lock quick-detach lever, which self-adjusts to the rail and returns the optic to zero when refitted, so it can be taken off for travel or cleaning and put straight back on.
What rail does this mount fit?
A MIL-STD-1913 Picatinny rail. The Auto Lock lever self-adjusts to in-spec and out-of-spec rails without tools.
How much does this mount weigh?
It weighs around 2.8 oz.
