So I've read the basics of zeroing and I'm relatively comfortable with the concepts and different options, ie 50/200, 100 etc.
I understand that the standard A2 rear site on most ARs is set for a zero from 300m-800m. So if one wants to set a 50/250 zero or 100 zero, than some elevation settings need to be changed on the rear sight so that POA will equal POI.
My Colt 6720 came with a flat top and pop up rear sight. The manual that came with rifle only discusses settings for the A2 carry handle type rear site, and the info I am familiar with online gives specific elevation changes for this same carry handle rear sight.
Is my flat top flip up rear site also configured from the factory for a 300-800m zero? I am interested in setting a 100 zero, but I am confused where to start and what changes to make.
