Holosun ARO-RD2 1x 2 MOA Red Dot Sight - Matte Black

The Holosun ARO-RD2 is a compact enclosed red dot sight built for rifles and carbines, featuring a crisp 2 MOA red dot reticle inside a streamlined matte black 22mm housing. Designed around a 22mm optical window, the ARO brings Holosun's proven performance into a lighter, lower-profile package that drops cleanly onto AR-15 platforms.

At its core, the ARO-RD2 runs a clean 2 MOA red dot with 1x parallax-free magnification and unlimited eye relief, so the dot stays locked on target regardless of shooting position. Power comes from a single CR2032 battery rated for up to 50,000 hours of runtime, with brightness adjusted through 10 daylight and 2 night-vision settings. Holosun's Shake Awake technology automatically wakes the LED when motion is detected and returns the optic to sleep during inactivity to preserve battery life.

The enclosed ARO housing measures approximately 2.48 inches long, 1.54 inches wide, and 2.63 inches tall, and tips the scales at just 3.38 ounces, keeping the optic lightweight on any rifle build. The included mount package supports both co-witness and low mounting heights, so it drops onto a standard AR-15 Picatinny rail straight out of the box. A matte black anodized finish keeps glare down and matches factory rifle furniture.

Backed by Holosun's reputation for reliable, feature-rich optics at a competitive price point, the ARO-RD2 is a strong value-oriented choice for any AR-15 or rifle build.
