Well Pete let's take this a little further. I just measured the front sight post with calipers and it is about 0.07", so I would need to move the post a distance about equal to its width. The tops of the "ears" have about 0.32" between them. So if I moved my post, which is now centered between the ears, one full post width, the post's centerline would then be .09" from the top of the left ear and 0.23" from the top of the right ear.
I guess what I'm getting at is that I don't like the front post to be that far off center (as stated in another's post - it's my "preference"). It ruins the sight picture for me. I want open space around my post. I don't want a sight base ear obscuring what is to the left of my front sight post. If it doesn't bother you, well then by golly that is great. I don't like it though. And neither did nearly every American combat rifle designer I assume, given that they put the windage adjustment on the rear.
Further, the adjustment is not limited by the ear itself, but but by the hole through which the sight post protrudes from the adjustment drum. By my measurements, the hole seems to allow 0.06" to either side of the post (total width of the hole is .19"-.21"). Don't you think it a bit odd that I must use all available adjustment (.06" to left) to get on target? I think 14" off at 100 yards is BS.
I just want to say thanks to everyone for their input on this thread. As I mentioned in my previous post, I am going with a windage adjustable rear sight and keeping my front post centered. Problem solved. I don't really need anymore input - it has been covered by the gracious and thoughtful members of this forum.
