Holosun ARO Green Dot – 2 MOA
The ARO replaced Holosun's long-running 403 and 503 tubes, and it fixed the thing that dated them: the window. A 22mm housing gives you noticeably more to see through than the old 20mm tubes, on a sight that still weighs almost nothing.
Green is the pick for shooters whose eyes struggle with red. It reads brighter to the eye at the same power level, and it stands out well against dirt, brush and brown targets. A 2 MOA dot is the precision choice. It covers two inches at 100 yards, so it doesn't hide a small target, and it's fine enough to shoot groups with rather than just point with.
It uses the Aimpoint Micro T1/T2 footprint, which is the most supported mount pattern in the business — Scalarworks, Unity, American Defense and LaRue mounts all bolt straight on. Two mounts ship in the box. Shake Awake powers the dot down after a set idle period and back up the moment the rifle moves, with the timeout adjustable or switchable off entirely.
