The Holosun HE510C-GR/HM3X is a compact optics combo that pairs the HS510C open reflex sight with the HM3X flip-to-side 3x magnifier. The sight offers Holosun’s Multiple Reticle System and Solar Failsafe for layered power redundancy, while the magnifier provides quick transition to 3x for extended target identification. This combination suits rapid target acquisition at close range with the option for moderate magnification when needed. Typical applications include everyday carry (EDC) and range/competition use where speed and the option for limited magnification are both valuable.
