This optic has a 1.41" optical center which is approximately an absolute co-witness for standard height AR iron sights. The Troy micro battle sights are lower than standard height iron sights so this red dot should be around a lower 1/3 co-witness with the Troy micro sights.

I was searching the web for this info and found it here! Thanks @Kabley for following up. I have Troy micros as well and I've been looking for an RDS that sits low and will co-witness. Here us some info I got from Troy CS.

"We make three sights; standard, medium and micro. The measurement to the center of the standard aperture is 1.36”. The measurement to the center of the medium aperture is 1.276”. The measurement to the center of the micro aperture is 1.16”. The standard & medium sights are meant for Mil-spec top rails and the Micros are meant for the enhanced weapons such as the IAR, Robinson armament XCR and other weapons with raised top rails."
