American Defense RMR LW QD Mount High 1.93 - Precision Quick-Detach Optic Mount for Tactical Excellence

The American Defense RMR LW QD Mount High 1.93 is a lightweight, quick-detach optic mount purpose-built for mounting red dot sights on AR pistols, short-barreled rifles, and other compact weapon platforms. Developed specifically for the Trijicon RMR, this single-piece mount delivers the durability of precision engineering without adding bulk or weight to your gun. If you run an RMR or similar small-frame red dot and need a rock-solid QD solution that doesn't compromise on height or performance, this is the mount purpose-engineered for your setup.

American Defense machined this mount from 6061 T6 aluminum and applied a hard coat T3 Mil-Spec anodize finish—the kind of no-nonsense construction that handles repeated deployment and daily use. The patented QD Auto Lock Lever system is the standout feature: it's designed to lock securely on both in-spec and out-of-spec rail systems, so you don't have to worry about fit variation across different guns. Adjustment is tool-free or requires only a finger or flat-blade screwdriver, and the lever can be oriented to lock toward the front or rear of the gun depending on your preference.

At 1.93" height, this mount positions your optic for a true lower third co-witness with most AR iron sights, giving you backup aiming references without obstructing your red dot view. The lightweight footprint keeps your overall gun balance intact—critical on a pistol-caliber carbine or pistol upper where every ounce matters. This is the kind of mount that earns trust through simplicity and precision: no proprietary tools, no over-engineered complexity, just a solid platform that locks on and stays locked.

Frequently Asked Questions

Will this mount fit my Trijicon RMR or SRO?

Yes. The AD-RMR-LW QD mount is purpose-built for the RMR and also fits the SRO and other red dots that share the same mounting footprint.

What does the 1.93" height mean, and will my iron sights co-witness?

The 1.93" height positions your optic for a lower third co-witness with standard AR iron sights, allowing you to see your backup iron sights below the red dot for redundancy.

Do I need special tools to attach or adjust this mount?

No. The patented QD Auto Lock Lever system is tool-free and can be adjusted with your finger or a standard flat-blade screwdriver. The lever can be configured to lock forward or rearward based on your preference.

Is this mount built to handle out-of-spec rails?

Yes. The Auto Lock Lever system is designed to secure reliably on both in-spec and out-of-spec mil-spec rail systems, giving you flexibility across different gun platforms.
