Holosun HM3X Magnifier

Turn your red dot into a fast, reach-capable aiming system with the Holosun HM3X 3X magnifier. Built for shooters who need instant target identification and tighter holds beyond close range, it adds 3x magnification without changing your optic’s familiar reticle or controls.

The HM3X pairs an aluminum-bodied, MAO-finished housing with a quick-release, ambidextrous flip-to-side Picatinny mount, so you can transition from 1x speed to magnified precision in seconds. A generous 2.75" (70mm) eye relief keeps your sight picture comfortable under recoil, while built-in windage and elevation adjustments let you align the magnifier precisely to your red dot’s zero. Holosun includes a spacer for compatibility with absolute and lower 1/3 co-witness heights, simplifying setups across common mounts and platforms.

Use the HM3X behind your rifle red dot for patrol rifles, competition stages, or range work where targets shift from near to mid-distance and you can’t afford to lose time swapping optics. With IP67 water resistance and operation from -21°C to 60°C, it’s engineered for hard use in real weather.

Backed by Holosun’s proven track record in duty-grade optics, the HM3X is a dependable magnifier solution that requires no batteries and minimal maintenance.
