The Trijicon RMR HD is a 1x red dot with a 3.25 MOA dot and a selectable 55 MOA segmented ring, so you can switch between a single crisp dot and a more complex reticle. Its housing is forged 7075-T6 aluminum and is waterproof to 66 ft. (20 m), so you can carry it in wet conditions. A forward-facing light sensor reads the brightness at the target in auto mode and adjusts the reticle to match, and nine brightness settings let you dial it in manually. The top-loading CR2032 battery gives up to 3 years of battery life and can be swapped without dismounting the optic.

Because it shares the RMR footprint, you can fit it to many pistols cut for red dots or to mounts you already own for the RMR; no mount is included. Larger, more tactile buttons and upgraded windage and elevation adjusters give audible clicks for tool-less zeroing. The window is larger and parallax free, so you can find the reticle with ease. Pineapple Ballistics coated this optic in Orange Cerakote over the factory unit, which gives it a bright color while the standard RMR HD features carry over.
