Holosun HM3X-MICRO 3x Magnifier

HOLOSUN logo

Pair it with your red dot and stretch your effective range without swapping optics. The HM3X-MICRO is a compact 3x magnifier built for rifles and carbines, adding fixed optical magnification behind red dot and reflex sights for mid-range engagements. A quick-detach flip-to-side Picatinny mount lets you swing the magnifier out of the way in an instant for close-range shooting, then flip it back when distance work calls. An included spacer supports both absolute and lower 1/3 co-witness red dot heights, and the ambidextrous design works equally well from either side.

Nearly 75% light transmission keeps the sight picture bright, and an adjustable diopter lets you dial in clarity for your eyes. Windage and elevation adjustments allow precise zero alignment with your red dot. Durable anodized aluminum construction and an IP67 rating handle the weather and the recoil, and at under 10 ounces the HM3X-MICRO adds meaningful capability without meaningful weight.

Includes HM3X magnifier, quick-detach flip-to-side mount, co-witness spacer, T10 tool, and user manual.
