Trijicon RMR HD Adjustable Red Dot Sight - 3.25 MOA, Black

The Trijicon RMR HD adjustable red dot sight is a combat-proven pistol optic built for shooters who demand reliability under real-world conditions. Whether you're running duty shifts, training hard at the range, or carrying defensively, the RMR HD delivers the speed and certainty of a true 1x red dot in a ruggedized package that fits where duty holsters expect it. At 3.25 MOA, the dot strikes the balance between sight picture clarity and target-covering efficiency that works across distances from contact range to 25 yards and beyond.

What sets the RMR HD apart is its forward-looking light sensor that reads the brightness at your target—not just ambient light—and adjusts reticle brightness automatically to stay visible without washing out or disappearing. You get nine standard brightness levels plus three night vision settings, and a new super bright mode for harsh daylight or reflective backgrounds. The reticle itself is switchable: choose a crisp single dot or a more complex aiming pattern depending on your preference, and both options work in daylight and NV. All that, and you can still manually dial illumination to suit your exact conditions.

Built from 7075-T6 forged aluminum, the RMR HD is waterproof to 65 feet and rated for extreme temperature swings (-40°F to 140°F), so it won't quit in desert heat, mountain cold, or field conditions. Tactile buttons and audible adjustment feedback make fine-tuning quick without fumbling; 1 MOA per click adjustments give you 135 MOA of total travel. The sight runs on a single CR2032 battery (included) with over three years of runtime on mid-level settings. It shares the same footprint as the original RMR, so it fits most existing duty-ready holsters without modification.

Trijicon's warranty card, manual, T10 Torx key, and mounting hardware round out the package. This is a red dot sight engineered for the shooter who won't accept compromise.

Frequently Asked Questions

Will the RMR HD fit my duty holster?

The RMR HD shares the same footprint as the standard RMR, so it's designed to fit most existing optics-ready duty holsters without modification. Always verify fit with your specific holster before carrying.

How does the auto illumination mode work?

The RMR HD features a forward-looking light sensor that reads brightness at your target—not just ambient light—and automatically adjusts the reticle brightness to remain visible in any condition. You can also manually override and set brightness to any of the nine standard levels, three night vision settings, or the super bright mode.

Can I switch between different reticles?

Yes. The RMR HD allows you to switch between a single crisp dot and a more complex reticle pattern. Both options include the new super bright setting and night vision capability.

What battery does it use and how long does it last?

The RMR HD runs on a CR2032 battery, which is included. At mid-level brightness settings (dot only), you can expect over three years of continuous runtime before replacement is needed.
