Yes, and no.
The UTE-2 allows for co-witness of the EOTech and the iron sights with the optic mounted on the receiver's A4 rail. The Tac Mt is too high. The Dominator places the EOTech a quarter of an inch higher than the receiver's rail would, taking it out of co-witness but still allowing the use of the iron sights through it. The Dominator was designed at the behest of the FBI to raise their EOTechs out of cowitness and clear up the sight picture.
