hey whats up . To co-witness is to be looking through your iron sights and the red-dot at the same time . If all is done right you get this .
It is important The red-dot is set to the correct hight so it will match up to your iron sights If you plan to co-witness . I have flip up iron sights . First I zero the iron sights then flipped them down . Next I zero the red-dot and when you flip up your iron sights the red-dot should be sitting right on top of the front post . I don"t like to co-witness . All's it seems to do for me is put stuff in my field of view that does not really need to be there . It is cool how when done correctly everything lines up thow.
If everybody has a problem with you and you have a problem with everybody .
It's not everybody that has the problem
