It is a perfect application for any normal height front sight unit.
The neat thing about the Dominator II is the fact that for example if you put an EOTech on it this is how it works!
Sight in the Iron Sights
Install the Dominator II on the Flat Top
While looking at the Iron Sights through the EOTech Screen with unit ON
Dial the Red Dot on reticle so it sets exactly on top of the front sight post and perfectly centered.
At that point you may only have to make a couple of slight adjustments to finalize the EOTech's Zero.
Than comes the good part!
At this point, you no longer have to look through the screen using the iron sights or even having them interfere with your view. You just look over the top of the front sight and rear sight about 1/4 inch at the Reticle on the EOTech ONLY!
Should you have a failure with the EOTech you just simply drop your head down looking through the Glass at the Iron Sights and you are automatically Co-Witnessed.
This eliminates two things if not using the Dominator and having Iron Flip Ups on the rifle. That is in this case should the Optic fail using Iron Flip Up Rear Sights. Normally one would have to flip up the rear sight. The problem being in a critical situation fine motor skills do not work well. But even more important than that is the critical time in a possible gun fight that it would take for the operator to flip up the rear sight at the same time dealing with adrenalin and the fine motor skill problems! With the Dominator you only need lower your head 1/4 inch to Co-Witness if the Optics fails. We found another thing that assists with the 1/4 inch head drop. It was that in a critical situation like your optics failing is the fact that any time we are threatened or something goes wrong in a critical situation we automatically drop our head. It is an involuntary action when threatened. Point being we found when you have an O.S. situation happen like your EOTech or optics fail and you need sights readily the head goes down. Just a little information on the Dominator II Rail and Sight System.
However using a Pro-Point on it could be a problem since the Pro-Points have a spacer in the mount that might make them a little too high for good Co-Witness using the Dominator II.
