The Holosun HM3X Micro 3x Magnifier with Absolute and Lower 1/3 Mount, Black is a magnifier.
The HM3X-MICRO delivers true 3× magnification in a compact, lightweight package designed for streamlined rifle setups.
Built for shooters who want the reach of a magnifier without adding unnecessary bulk, it provides clear glass, fast transitions, and dependable durability behind today’s most popular red dot sights.
A magnifier sits behind a red dot or holographic sight to add magnification, and flips to the side when you want the unmagnified view. Check the mount height matches your sight.
