Holosun HM3X 3X Magnifier | Flip-to-Side Mount | Granite Ridge Defense

The HM3X is an aluminum bodied 3X magnifier designed for use in conjunction with a red dot sight. The HM3X is feature-packed and includes a quick release, ambidextrous, flip-to-side Picatinny rail mount. Holosun includes a spacer with the HM3X that provides compatibility with absolute and lower 1/3 co-witness dot heights for maximum compatibility. The HM3X has a generous 2.75” of eye relief, is IP67 certified water resistant, and includes windage and elevation adjustment for precision zeroing to your optic’s zero. The HM3X also includes a built-in flat driver tool for easy adjustments.

Granite Ridge's Take

The Holosun HM3X adds 3X magnification behind a compatible red dot while retaining the ability to move the magnifier out of the sight line when it is not needed. The included quick-release flip-to-side mount and spacer support common absolute and lower-third optic heights, making it an easy way to add versatility to a red-dot-equipped rifle. This is a great budget friendly option for adding magnification to you're optic system. Too long for your rifle? Check out the HM3X Micro for more rail space.
