The Holosun ARO-EVO 2 MOA red dot is an enclosed rifle sight that moves the Advanced Rifle Optic platform to a larger 26mm viewing window (brand part no. ARO-EVO-RD2). Its 2 MOA dot is parallax free with unlimited eye relief, so you can shoot it with both eyes open. A solar panel backs up the battery, and Shake Awake wakes the sight when the rifle moves. Holosun includes two mounts, so one box covers a lower 1/3 co-witness or a lower-profile setup on a flat-top rifle. It is a rugged 6061 aluminum optic aimed at carbines and general rifle use.

Key Specifications

• The reticle is a 2 MOA red dot from a 650nm LED, small enough for precise aiming and fast at close range.
• Magnification is 1x with parallax-free optics and unlimited eye relief, which suits shooting with both eyes open.
• The viewing window is 26mm (1.02 inches in diameter), a larger opening than earlier ARO models for a wider field of view.
• The housing is 6061 aluminum with a black hard-anodized finish, built to take rifle recoil.
• The sight is rated IPX8 waterproof with 1000G vibration resistance.
• Power comes from a CR2032 battery in a side-loading tray, so you can swap it without removing the optic, with up to 50,000 hours at setting 6.
• Brightness offers 8 daylight and 4 night vision compatible settings, plus a lockout mode that prevents accidental changes.
• An adaptive brightness system adjusts the dot automatically, and the solar failsafe adds backup power from the panel.
• Shake Awake powers the sight up when it detects motion and lets it sleep when idle to extend battery life.
• Two mounts are included, a 1.63-inch lower 1/3 co-witness mount and a 1.05-inch low mount, both for Picatinny rails.
