The ARO addresses the size versus viewing area compromise found in other micro red dots by maximizing the window while minimizing the housing footprint. This design allows it to fit optics-ready pistol slide cuts while providing an unobstructed sight picture. The Fastfire/Venom footprint ensures compatibility with the widest range of pistols, rifles, and shotguns using adapter plates or direct mounting.

Frequently Asked Questions
Q: How do I mount the ARO to my pistol?
A: The easiest way to mount the ARO to a pistol slide is by using an adapter plate in the Fastfire Pattern. AT3 carries adapter plates that can be used simply by drifting out the rear sight of many popular pistols on the market. The ARO may not fit in pistol slides cut specifically for Fastfire red dot sights.
Q: How do I know which riser mount to get?
A: For AR’s and other modern rifle platforms, we recommend the .83″ Mount if you are running without iron sights since it puts the red dot at the standard height of mil-spec iron sights. If you’re running a shotgun, pistol, or any firearm with a “drop comb” where the cheek rest is lower than the top of the receiver, the Low Mount will serve you just fine.
If you go with the .83″ Mount, you’ll also get the Low Mount – if you plan to move the optic around multiple platforms, go with that option!
Q: Do I need to use iron sights along with the ARO Red Dot Sight?
A: NO – Iron sights are not required to use this red dot sight! The red dot sight can be used on its own. Many people choose to use iron sights as a backup, but they are optional. This red dot sight will work great on “optics ready” rifles that don’t have any iron sights.
Q: What is the recommended torque for the top screws that thread into the mount? Do I need Loctite/threadlocker?
A: We recommend no more than 12 inch-lbs for torque on the two top screws, no matter what you’re mounting the ARO to. You do not necessarily need threadlocker, but it is highly recommended, especially on handguns. A small drop of Blue Loctite or equivalent medium threadlocker on each screw will suffice.
AT3’s Most Versatile Red Dot
The ARO Reflex Sight is able to be directly mounted to many popular “Optics Ready” pistols on the market that utilize a Burris Fastfire/Vortex Venom mounting pattern – either directly on the slide or via an adapter plate
