Brass Facts goes over the Holosun ARO (Advanced Rifle Optic) that is said to be set to replace the popular Holosun 403 series, with the objective of redefining expectations for budget-friendly red dot optics. While maintaining a similar price point to the 403, the ARO introduces significant improvements in design and performance.

Moondog Industries reviews the AT3 Tactical ARO Red Dot Sight which he finds is not too bright... "I found the fit and build on the ARO to be excellent. There was a slight blem in the paint job of the co-witness mount, it was not visible when the red dot was mounted. It was designed to fit Burris Fastfire/Vortex Venom compatible mounts and slides (check their website for a list of compatible pistols and slides)."
