Holosun ARO 2MOA Red Dot Reticle with HM3X 3x Micro Magnifier with QD Flip
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.

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.
