ARO RD | Holosun (PTA stock)

Holosun ARO-CORE-RD-2 is a compact and lightweight enclosed red dot sight designed for modern rifles, carbines and pistol-calibre carbines. Its refined 22 mm optical window provides a clear sight picture, while the precise 2 MOA red dot supports fast target acquisition and accurate shot placement at short and medium distances.

The simple dot-only reticle keeps the sight picture clean and uncluttered. With 1× magnification, unlimited eye relief and a parallax-free optical system, the ARO-CORE-RD-2 allows comfortable aiming from different shooting positions.

Holosun Shake Awake technology automatically activates the reticle when movement is detected and switches it off during inactivity. Combined with a CR2032 battery and runtime of up to 50,000 hours, this provides dependable performance while reducing unnecessary battery consumption.

Ten daylight and two night-vision-compatible brightness settings allow the reticle intensity to be adjusted for different environments. The side-loading battery tray also makes replacing the battery quick and easy without removing the optic from the firearm.

The durable aluminium housing features a protective MAO finish, IP67 water resistance and 1000G vibration resistance. Its compact 3.38 oz body keeps additional weight to a minimum while remaining suitable for demanding range, competition and professional applications.

Both a 1.63-inch lower 1/3 co-witness mount and a 1.05-inch low mount are included, providing flexible installation across different Picatinny-equipped platforms.
