The Holosun Technologies ARO-MRS-GD ARO enclosed red dot sight delivers a compact aiming solution for rifles and other compatible platforms. Designed as an upgrade to Holosun’s popular 20mm 403 and 503 series optics, the ARO features a durable 22mm housing that pairs cleanly with Holosun magnifier systems. Its enclosed design helps protect the emitter and reticle from environmental exposure, while the black finish provides a professional appearance for a wide range of firearm setups.
The ARO uses a 1X optical configuration for rapid target acquisition and a multi-reticle system that gives shooters flexibility when selecting their preferred aiming point. The red dot format supports both-eyes-open shooting and helps maintain situational awareness during close- and medium-range applications. The included 1.63-inch lower 1/3 co-witness pedestal mount positions the optic for compatibility with many standard-height iron sight configurations.
Built for streamlined integration, the Holosun ARO-MRS-GD combines enclosed red dot performance with a housing profile suited to magnifier use. Its 22mm objective provides a clear sight picture while preserving a compact footprint on the firearm. Whether used as a primary optic or paired with a magnifier, this Holosun Technologies ARO model offers a practical balance of versatility, durability, and fast sight alignment. Mounting hardware and firearm compatibility should be verified before installation.
