Product description

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

The best mount out there. I have 2 now and would have no problems with purchasing anything at3. I wish they came with some stickers... I look forward to future purchases, thank you for the superb service.

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

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

I have a Hawke micro reflex and it works for that as well. Fits snug with perfect co witness of BUIS. For me the supplied screws could have been a few threads longer but still worked. Probably because of the bran optic I'm running. But overall great product for the price.

Initially received the first riser but there was a small defect with one of the base plate threads. The company promptly sent a replacement and the unit works as advertised! Thanks for the great customer service!

I use this in a 22lr conversation AR. Perfect optic for this use.

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!

Charles Lake Verified buyer
Good product just had a rough start

When I got the mount the holes weren't properly tapped for the supplied screws just ran a tap through the holes and everything mounted up solid

Would definitely buy again
