I am using an Aimpoint T-1 w/LRP Mount & Spacer. I have tried getting the sight pictures in that pic with a Daniel Defense DD 1.5, a LaRue quick detachable fixed rear sight (the number escapes me right now), and the LMT M16A2 style rear sight (the one that looks like the chopped carry handle).
I have not been to the range to zero anything yet. I've just been experimenting with whether or not to go with folding or fixed rear sight and so I've been trying out different rear sights and the resulting sight pictures.
It seems that if the dot is centered in the Aimpoint then the dot is above the front sight post (fine since the rear BUIS is not being used), and the loop of the rear sight is canted. Then when I lower my head to look through the rear aperture, nothing remains lined up and I have to re-orient everything to get the dot centered, etc.
What am I doing wrong?
Will this tend to correct itself when I get the irons and the Aimpoint zeroed?
I wear pretty thick glasses, so I appreciate being able to hold my head high to see the dot in the Aimpoint. I also appreciate being able to "index" the dot to the front sight post although I understand some people say you shouldn't or shouldn't have to do this. But it's not going to do my any good to zero all the elements together unless I can get a good sight picture with the dot centered in the irons.
I was told years ago by an eye doctor that my eyes do not work together so I'm wondering if that's my answer right there.
Right now I'm ready to concede that the irons on my carbine will only be used if the red dot goes down, but I was really wanting to try out a cowitness.
Anybody? Am I doing something wrong?
The first thing I'm going to tell you that might clarify things is that the Aimpoint is parallax free, simply stated, you don't have to center the dot inside of the optic. Just put the dot where you want to shoot.
You have the LRP with spacer which puts the iron sights in the bottom 1/3 of the optic glass, so when not looking through your rear sight the dot SHOULD be above the front sight post.
When you look through your rear sight, if your irons and optic have been zeroed to the same distance the dot should sit on the tip of the front sight and be centered (or close to it). I say close to it, because my dot has always sat on the tip, but just a little to the left of my front sight. That's on two separate rifles with different type iron sights. I have always zeroed my irons, brought the dot as close as possible and then zeroed the optic independently.
Hope this helps.
