I've got a Dominator, and while I really like it, I think it would be a poor choice to try and add "QD" thumb screws and such. You can remove the EO from the mount, but removing the Dominator too just doesn't seem practical. My Dominator is blue loc-tited in place, and I can't imagine how it would be repeat-zero capable.
If you need a fixed rear BUIS for your dedicated EOTech rifle, the Dominator is perfect. If you're going to be using other optics, I'd strongly suggest a different platform that was DESIGNED for QD and repeat zero.
