Magnifier HM3X-MICRO 3x with QD Picatinny mount HOLOSUN

The Holosun HM3X-MICRO 3x Magnifier, instant magnification in a compact and robust format

A 3x Magnifier designed to pair with a red dot sight

The Holosun HM3X-MICRO 3x is a fixed-magnification optical Magnifier designed to be used directly behind a red dot sight mounted on a Picatinny rail. It is aimed at airsoft players who want to instantly switch from x1 aiming to 3x magnification, without changing their setup or removing their primary sight. The side-flip QD mount, integrated into the Magnifier body, allows the magnification to be folded away or reactivated with a single motion, to the left or right depending on the shooter's preference.

The 7° field of view provides a consistent aiming window at 3x, while the 67 mm eye relief ensures comfortable eye positioning, even when wearing protective gear. The diopter adjustment, adjustable from +3 to -3, allows each user to adapt image sharpness to their own visual acuity, without any tools.

6061-T6 aluminum construction and IP67 protection

The HM3X-MICRO body is machined from 6061-T6 aluminum and treated with hard anodization (MAO treatment), which gives it increased resistance to abrasion and impacts. The unit is nitrogen-filled to prevent internal fogging and moisture ingress. Waterproofing is certified to IP67, meaning the Magnifier can withstand temporary submersion. Vibration resistance is rated at 1000 G, a value that reflects a construction designed for demanding conditions.

Operating temperatures range from -30°C to +60°C, and storage temperatures from -40°C to +70°C. These specifications place the HM3X-MICRO in a category of Magnifiers built to last in the field, regardless of the season.

Integrated QD mount and configurable co-witness

One of the distinguishing features of the HM3X-MICRO lies in its integrated side-flip QD mount, usable by both right-handed and left-handed shooters. This mount is directly attached to the Magnifier body: no adapter or separate mount is required. The optical axis height is set at 35.8 mm, allowing alignment with the majority of standard-height red dot sights, such as the Holosun HS510C or the HE403C.

Absolute co-witness is accessible directly with the included mount. A riser spacer, included with the product, allows switching to a lower 1/3 co-witness configuration depending on the height of the paired sight. The compact dimensions of the Magnifier, 70 x 46 x 62 mm for a weight of 235 g, limit bulk on the replica and preserve the overall balance of the setup.

A Magnifier designed for airsoft and sporting use

The fixed 3x magnification is well suited to common engagement distances in airsoft gameplay, where the ability to quickly identify a target at medium range provides a real advantage. The ambidextrous side-flip of the integrated QD mount makes the transition from open to magnified aiming particularly fast, without leaving the shooting position.

The MAO treatment, nitrogen fill and IP67 certification give the HM3X-MICRO durability suited to field conditions, whether playing outdoors in the rain or in a dusty environment. For players who already use a red dot sight, the HM3X-MICRO represents a coherent extension of their optical setup.
