The Trijicon RMR HD is the next-generation RMR — the same legendary toughness with major upgrades: a top-loading battery (no need to remove the optic), a forward-facing light sensor for smarter auto-brightness, and a larger, clearer window. This model offers a switchable 55 MOA circle with a 3.25 MOA centre dot.
Run the full circle-dot for fast acquisition or the dot alone for precision. The RMR HD is built on the durable RMR platform and is RMR-footprint compatible for wide pistol fitment.
