The Trijicon RMR® HD (Type 3) is a high-performance red dot optic crafted to serve the demanding requirements of military, law enforcement, and serious shooters. Building on the legendary RMR platform, the HD version elevates durability, visibility, and usability — engineered for rapid target acquisition and survival in operational environments.

Key Performance Features:

• Advanced Build — Constructed from 7075-T6 forged aluminum, this optic withstands rugged use, designed to divert impact away from the lens; waterproof up to 66 feet. 

• Smart Brightness Control — A forward-mounted light sensor dynamically adjusts the reticle’s brightness based on the target’s lighting, minimizing washout in any condition.

• Dual Reticle Display — Choose between a precise 3.25 MOA dot or a broader 55 MOA segmented circle-dot for versatile acquisition in any scenario. 

• Versatile Illumination Settings — Manual brightness includes 9 daylight, 3 night-vision-compatible settings, and a “super-bright” option. Auto-brightness modes include Normal, High, and Low. 

• Enhanced Controls — Large, tactile buttons offer audible feedback even when wearing gloves; includes button lockout and brightness memory modes.

• Optimized Sight Picture — A prominent index ridge aids rapid alignment from unconventional angles, while the same mounting footprint ensures compatibility with RMR-ready holsters.
