AT3 ARO™ Micro Red Dot Reflex Sight with Optional Riser Mount

AT3 ARO™ Micro Red Dot Reflex Sight

$119.99

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

Get Some! Or just get one.

Mount seems very secure and sturdy. Vortex Venom fit perfectly with almost no slop before the hardware. She's mounted to my BRN-180s with Daniel Defense Iron Sites and it just completes the look of this Build! Absolutely love it!

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Perfect riser

Perfect height riser for the venom to co-witness some backup flip sights. Very good quality for the price, well worth the money. I actually have it on a Kel-tec KS7 shotgun; so far so good. Puts the sight right where I want it

Thanks for taking the time to share your feedback. We're glad we are satisfied with your purchase!

Great for Burris Fast Fire 4

Shipping was very prompt. My Burris Fast Fire 4 fit perfectly and tightly to the AT3 riser base plate. Cowittness alignment with the Burris reflex red dot and my PSA upper A3 front sight was "spot on". (all puns intended) I would definitely recommend this mount to a friend. Joe in El Paso, Texas

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
