Height above boreline

[rob_s]

Does anyone know the precise height above boreline for the following:
Eotech 512 series
iron sights
Larue 1/3 cowitness aimpoint mount

all mounted on a flattop AR?

Rob going from memory so re-verify with someone else.
EOTECH 2.6in
Irons 2.5in
no idea on the Larue

Believe Pat Rogers would probably have that info.

I thought irons and Eotech were 2.6", and the LaRue around 2.8".

Since irons and Eotech provide absolute cowitness they should be the same.

I believe HOB is as follows:

A1/A2 = 2.5"
Flat top = 2.6" (This is why you need an F marked front sight base)
Aimpoint M4 in Larue Tall mount = 2.79" (1/3 co-witness)

A red dot with absolute co-witness would still be 2.6"
