The Holosun ARO 2 MOA Red Dot + HM3X 3x Magnifier combo is basically a simple 1x red dot that can instantly turn into a mid-range setup when you flip the magnifier in. The ARO gives you a clean, fast 2 MOA red dot in a wide 22mm window for close work, and the HM3X adds 3x magnification on a quick flip-to-side mount for stretching things out when you need more precision. Both pieces are built from solid aluminum, come with quick-detach mounting, and are designed to line up properly with included spacers so the sight picture stays clear and centered. It’s a flexible, grab-and-go rifle setup that covers both close-quarters speed and longer-range clarity without needing a full scope swap.

DESCRIPTION

Holosun ARO 2MOA Red Dot

ARO (Advanced Rifle Optic) is an advancement on the popular 20mm 403 and 503 series optics. ARO features an all-new 22mm housing design that mates perfectly with the magnifier series and an all-new 1.63” lower 1/3 co-witness pedestal mount.

HM3X 3x Micro Magnifier

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.

FEATURES

Holosun ARO 2MOA Red Dot

Shake Awake™ Technology w/ Last Setting Recall

Shake Awake Technology is a standard feature on all current model Holosun optics and serves to extend battery life by deactivating the optic’s LED while not in use. A highly sensitive motion sensor works to detect motion keeping the LED powered on during use. This allows for duty or concealed carry with seamless operation throughout your day or shift. At the end of your day or shift when your firearm is stored, the motion sensor will detect a motionlessness state and after 10 minutes (default setting) Shake Awake Technology powers the LED off until motion is again detected. Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred. The slightest touch of the optic instantly reactivates the LED so your Holosun optic is ready when needed.

Multilayer Reflective Glass

Holosun’s use of Grade 5 Titanium in certain Elite category optics and laser devices results in unparalleled strength and durability. Holosun Grade 5 Titanium has more than double the tensile strength and has five-times the fatigue strength of 7075 Aluminum. Grade 5 Titanium is also able to withstand the corrosiveness of seawater making Holosun Titanium model optics and lasers suitable for use in maritime environments.
