I dont think there is a right or wrong way. It just comes down to personal taste.

The only reason I am taling about this, is because the are specs and requirments being driven on of this term "Co-Witness" and no one can agree on what it is and most will argue until they are blue in the face that there's is the one "TRUE" meaning of co-wintessing.

I thought the term co-witness meant that looking through your optic you could align the irons, preferably in the bottom 1/3 to 1/4 of the window. Some guys like their dot sitting right on the front sight post. To me that way is distracting.
Here's how I do mine:
I zero my optic 50yd POA/POI, turn it off. Then zero my irons 50yd POA/POI and I'm done. Irons I use for those times I'm a dumbass and forget to turn the optic on or it goes dead.

I zero my irons first.
Then I zero my optic.
When using my preferred red-dot optics (Aimpoints in LaRue mounts) in every case to date, the red-dot has been perfectly centered on the iron sight front post tip when looking through the irons and optic simultaneously. In other words, my irons and red-dot have the same POA/POI and are CO-WITNESSED.
If my red-dot and BIS have been co-witnessed during the initial zero, then at the beginning of each shift/operation I can flip-up the BIS and ensure the red dot is co-witnessed as a quick verification that my zero has not shifted. Then I flip-down the BIS and go about my business. In my world, that is the main benefit of co-witness.

I think that however it's ultimately defined, co-witnessing does involve being able to see and use both systems at the same time.
As an alternative and to put a Pat Rogers spin on it, "...co-witnessing is watching TWO hot chicks get it on...."
brett, do you have a pic of that SOPMOD target? is it specifically for the aimpoint, or another optic?
i always understood co-witnessing to mean that you can see the irons through the optic window, whether they be centered or in the lower third, and that when looking through the irons, the dot would be adjusted to coincide with that sight picture (sitting right on the front sight), or vice-versa, which would give you the same POA/POI as long as you look at the dot through the irons at any distance.
once you look at the dot ABOVE the irons, then the POI will be the same as the POA only at that zero distance (25M). at any other distance, there will be a slight divergence proportional to your eye's height above the iron sight line.
I guess this is what I am saying. and I think everyone here has shown that there is NO true ONE definition to a "Textbook" or Doctrine to a actual Co-Witness. Its amazing to me that a term that is so widely used and thrown around as "must have" when buying optics and BUIS is a true unknown.
