So is there a standard for Height over bore for an AR using an Eotech XPS? I seen a lot referencing 2.6", but I assume that's referring to the carry handle?

 

Anyone have anything I can reference or know the answer?

The only standard i know of when mounting an optic on a rifle is the lower the better. Minimizing the angle difference between the optic and the barrel means that you can adjust to further and closer ranges with less variation in POA. For instance, if you had it mounted on the upper receiver rail, and have it zeroed at 100 yards and shoot at 200, you will have to compensate less for POI then say if you had the optic mounted on the top of a carry handle.
