Optimize the ARO for your AR15 with this Sleek, Minimalist Fastfire Compatible Riser Mount
In the world of open micro reflex sights, the small profile can provide a serious advantage in overall visibility. With no bulky housing tubes or adjustment dials in the field of vision, mounting a small red dot on an AR pattern rifle makes for a very pleasant shooting experience. The AT3 ARO Absolute Cowitness mount pushes the optic further forward on your rifle, and raises the ARO red dot sight to absolute cowitness height with backup iron sights. This enables use with any of our AT3 magnifiers, and many other accessories.
This riser can also be used for for your Fastfire, Venom, or Docter red dot sights.
Red dot sight is not included.
Specifications:
- Mounts on any Picatinny rail
- Fastfire Compatible Mounting Pattern
- Machined from aircraft aluminum with black anodizing
- Weight: 1.1 oz
- Includes Allen wrench
- Backed by the AT3 Lifetime Warranty
