Holosun HM3X Micro with QD Mount

• Compact 3x magnification: adds useful reach behind a red dot sight for clearer target identification at intermediate distances without making the rifle feel front-heavy.
• Flip-to-side QD mount: lets the magnifier move out of the optical path instantly, so the carbine can switch from close-range speed to magnified aiming in seconds.
• 67 mm eye relief: gives a forgiving head position that is easier to maintain in improvised shooting positions and during fast target transitions.
• Absolute and lower 1/3 co-witness compatibility: the included spacer helps match common red dot mounting heights, simplifying setup across different rifle and optic combinations.
• Nitrogen-purged, IPX-7 construction: sealed, fogproof housing keeps the sight picture clear in rain, humidity, and temperature changes encountered in field or range use.

About the Holosun Magnifiers Series

Holosun Magnifiers are built to work alongside red dot optics on rifles and carbines, giving shooters a simple way to extend practical aiming distance without giving up the speed of a non-magnified sight. Within Holosun’s lineup, the series covers both 3x and 6x options, allowing users to choose between a more compact setup or greater target detail for longer shots. The family currently includes the HM3X, HM3XT, HM3X-MICRO, and HM6X, with aluminum or titanium housings depending on model.

A defining trait of the series is the flip-to-side quick-detach mount, which keeps transitions between magnified and unmagnified views fast and intuitive. Holosun also designs these magnifiers around absolute and lower 1/3 co-witness heights, so they integrate cleanly with many modern red dot configurations. In practical use, the series is aimed at shooters who want more precision and better target recognition at distance while preserving a familiar carbine handling style. The result is a line of magnifiers that emphasizes compact dimensions, straightforward mounting, and compatibility with common tactical optics setups.

About the Holosun HM3X Micro with QD Mount

The Holosun HM3X Micro with QD Mount is the most compact 3x option in the Holosun magnifier range, built for shooters who want added distance capability without the bulk of a larger magnifier. Its true 3x magnification helps sharpen target detail and makes holds or precise shot placement easier at intermediate ranges, while the smaller body keeps the rifle balanced for fast handling. That makes it a strong fit for general-purpose carbines, training rifles, and tactical optics setups where both speed and flexibility matter.

The optical layout is tuned for practical use behind a red dot. A 7° field of view gives enough surrounding image to stay aware of the scene, and the 67 mm eye relief is forgiving enough for quick mounting and positional shooting. The ±3D diopter adjustment lets the user fine-tune image sharpness to individual eyesight, which is especially helpful when the magnifier is paired with a crisp dot and used for longer observation or repeated strings of fire.

Mechanically, the HM3X Micro is designed around speed and adaptability. Its flip-to-side quick-detach mount allows immediate transition back to an unmagnified sight picture, and the included spacer supports both absolute and lower 1/3 co-witness heights. The aluminum housing, fogproof construction, shock resistance, and IPX-7 waterproofing make it suitable for hard outdoor use, while the compact 227.00 g weight helps preserve the handling qualities that make a red dot-equipped rifle effective at close range.
