The Trijicon RMR HD is a premium red dot sight designed to meet the demands of military, law enforcement, & civilian shooters. Building on the legacy of the RMR Adjustable LED model, the RMR HD features a larger, unobstructed field of view & a forward-looking light sensor that automatically adjusts the reticle brightness based on ambient lighting. The sight offers a selectable reticle, combining a 55 MOA segmented circle with either a 1.0 MOA or 3.25 MOA center dot, providing versatility for close-quarters engagements & precise long-range shots. Its patented housing shape, made from forged 7075-T6 aluminum, delivers exceptional durability & shock resistance. The Trijicon RMR HD is engineered for reliability & ease of use. It features a top-loading CR2032 battery that provides over three years of continuous use at a mid-level brightness setting. The optic includes manual & automatic brightness modes, with nine brightness settings, including three night vision & one super bright option. Upgraded windage & elevation adjusters ensure precise zeroing, while compatibility with existing RMR footprints allows seamless integration with a wide range of firearms. Trijicon’s commitment to quality ensures the RMR HD is ideal for competitive shooting, tactical operations, & everyday carry.
