Title: Absolute Co-Witness vs. 1/3
Post by: gsmgc on May 08, 2013, 09:10:56 PM

Hi all,

Regarding the co-witness of your red dot and iron sights.

Absolute or 1/3? Which one and why?

Absolute. 

My cheek weld using the BUIS have me using the red dot at absolute co-witness.  It's a more natural feel than 1/3.  If I used less cheek weld, then the 1/3 co-witness would probably be more natural.

From what I've seen, you practice setup using the BUIS, and then choose the co-witness level that matches whichever cheek weld is more comfortable for you.

YMMV

Fixed irons, particularly the front, lower 1/3 cowitness. Folding irons, absolute cowitness. That said, I no longer have any guns set up with folding irons and absolute cowitness. All my guns currently have either a FSP or DD fixed front sight.

Absolute + folding irons = perfection.
