Product description
Unity Riser Mount for EOTech EXPS3 and More
This riser from Unity Tactical comes optimized for use with Lower 1/3 Cowitness Optics, raising them to a 2.26″ optical center line. Any optic with a Lower 1/3 height works with this mount, but there it really shines is with the EOTech EXPS line of weapon sights, or any other large-window optic with the same height.
Why 2.26″ Optic Height?
Unity Tactical produces FAST mounts at this height specifically for duty use. This height allows faster and easier target acquisition when wearing bulky equipment like night vision goggles, gas masks, and ear protection/communication headsets. Unity considers this height optimal for professional use cases.

Questions & Answers 1

I wonder if this could be used to raise a 5-25x56 without sacrificing too much accuracy. Any thoughts?
Greg Ray · Apr 5, 2026AT3 Support Team — No, the Unity Tactical FAST Optics Riser is designed for red dot sights like EOTech EXPS (lower 1/3 cowitness), not high-power variable scopes like a 5-25×56—the extreme height (2.26") would create an unstable, non-ideal cheek weld, likely sacrificing accuracy and comfort.
