AT3 Tactical ARO Absolute Cowitness Cantilever Riser Mount Review

First Impressions of AT3 Tactical ARO Absolute Cowitness Cantilever Riser Mount

The AT3 Tactical ARO Absolute Cowitness Cantilever Riser Mount promises to solve a common problem for AR platform users: optimizing red dot sight placement for improved visibility and accessory compatibility. Made by AT3 Tactical, this mount aims to provide an absolute cowitness with backup iron sights while pushing the optic forward for better use with magnifiers. This seemingly simple piece of kit has the potential to drastically improve a shooter’s experience.

I’ve struggled with finding the optimal balance between optic height and forward positioning on my AR-15 for years. Many mounts either placed the red dot too low, obstructing my view with the iron sights, or didn’t offer enough forward extension to comfortably use a magnifier. The promise of an absolute cowitness combined with a cantilever design immediately piqued my interest.

Upon unboxing, I was impressed by the AT3 Tactical ARO Absolute Cowitness Cantilever Riser Mount’s clean, anodized finish and solid feel. It’s lightweight, but the aircraft aluminum construction inspires confidence. The included Allen wrench was a nice touch, showing AT3 Tactical’s attention to detail.

I considered a few similar mounts from other manufacturers, including those from Primary Arms and Midwest Industries. However, the AT3 Tactical mount’s price point and specific design for absolute cowitness with the ARO red dot, as well as Fastfire, Venom, or Docter red dot sights, ultimately swayed me. I was cautiously optimistic that this would be the perfect solution to my red dot mounting woes.

First Use Experience

I first tested the AT3 Tactical ARO Absolute Cowitness Cantilever Riser Mount at my local shooting range, mounting it on my AR-15 with a red dot sight and backup iron sights.

The mount performed flawlessly, providing a clear and unobstructed view through my red dot. The absolute cowitness was spot-on, allowing me to easily transition to my iron sights without adjusting my cheek weld. There were no surprises; the mount did exactly what it was designed to do.

After several range sessions and a weekend training course, the AT3 Tactical ARO Absolute Cowitness Cantilever Riser Mount has proven to be incredibly reliable. There are no signs of loosening or shifting, despite consistent use and recoil. The anodized finish has held up well against minor bumps and scratches.

Cleaning is simple; a quick wipe-down with a microfiber cloth is all it takes to remove any residue. Compared to some other mounts I’ve used, this one requires minimal maintenance. It has exceeded my expectations in terms of durability and consistent performance.
