cowitness and lower 1/3 co witness

[SideShow Bob]

What is the RD mount height ?

And according to Brutal, I am talking out my Arse on this,
Brutal you hurt my little feelers, I'm going to report you to the Mods !

And I possibly could be, this setup for me has worked great with my EoTechs before everything was lost in the "Great Floods of 2013.......

Go shoot your setup and see how it does, if it works good, don't fix what ain't broken......

I am so frustrated. How could this be lower 1/3 co witness with the sights and red dot right in the very center?

It's not, you must have the shorter mount, so you have absolute co-witness. Lower 1/3 would be a taller mount to where your iron sights line up in the lower 1/3 of the optic.
