The ARO Enclosed Rifle Sight expands on Holosun's popular 403 and 503 optics, providing both-eyes-open, fast-engagement functionality with no parallax, unlimited eye relief, and a dozen brightness settings, including two that are night-vision compatible. The 22mm lens matches perfectly with optional Holosun magnifiers for those longer shots. The sight uses shake awake activation and shuts off automatically after being motionless for 10 minutes.
Multicoated optics ensure you'll get a clear, high-contrast view. The red dot reticle has a 100 MOA windage and elevation adjustment range at 1/2 MOA per click and comes with a lower 1/3 co-witness mount that puts the optical center at 1.63" above the rail. One CR2032 battery will power the ARO for up to 50,000 hours.
