Holosun HM3XT Magnifier

Extend your red dot’s capability without adding bulk. The Holosun HM3XT is a compact 3X magnifier with a full titanium housing, built to give you fast target identification and better hit probability at distance while keeping your rifle setup streamlined.

Designed to pair behind a reflex sight, the HM3XT delivers 3X magnification with a generous 2.75 in (70 mm) eye relief for comfortable, heads-up shooting. Its ambidextrous flip-to-side, quick-release Picatinny mount lets you transition instantly between 1x speed and magnified precision, and the included spacer supports both absolute and lower 1/3 co-witness heights for broad optic compatibility. Precise windage and elevation adjustments help align the magnifier to your dot’s zero, with a built-in flat driver tool for easy field tweaks.

Use the HM3XT for patrol carbines, training rifles, competition stages, or duty setups where you need rapid close-range engagement and the option to read targets farther out. With IP67 water resistance, -20°C to 51°C operating range, and 1000G vibration rating, Holosun builds this magnifier for hard use in real-world conditions.
