Description

The Holosun ARO in Flat Dark Earth (ARO-RD2-FDE) is the compact 1x rifle red dot with a 2 MOA red dot, finished in FDE to match a tan or earth-toned build, on a 1.63 in lower 1/3 co-witness Picatinny mount.

Everything the black ARO does, in a finish that does not stand out on an FDE rifle.

A CR2032 rated at up to 50,000 hours powers the dot, and Shake Awake turns it off when the rifle is still and back on as soon as it moves. The battery loads from a side tray, so changing it does not mean removing the optic. There are 10 daylight and 2 night-vision compatible brightness settings, 0.5 MOA clicks and 50 MOA of travel each way.

The aluminium housing has a MAO finish and an IP67 rating. Eye relief is unlimited, so you can use it with both eyes open from any comfortable head position. The same sight in black is the ARO black.

Why shooters choose the ARO in FDE

  • Finish — Flat Dark Earth housing and mount
  • Reticle — single 2 MOA red dot
  • Battery — CR2032, up to 50,000 hours, side-loading
  • Shake Awake — saves battery automatically
  • Mount — 1.63 in lower 1/3 Picatinny included

What the ARO FDE fits

The mount clamps to any MIL-STD-1913 Picatinny rail, giving lower 1/3 co-witness over AR-height irons on AR-15s, straight-pull rifles and railed shotguns. It also suits lower 1/3 flip-to-side magnifiers.
