Default TA01NSN iron sight

Just recently bought a new ACOG model TA01NSN which comes with iron sight on the top. Upon opening I immediately noticed that the front sight seem to be way to the right. I thought maybe I got a bad one but after looking at the factory pictures online it appears they are supposed to be that way. A couple questions, why are they set up that way and how exactly do I use it? I looked up the included manual and it mentioned nothing about their iron sight.

Default TA01NSN iron sight

Don't own one nor looked through one but maybe due to quicker/natural swapping between the iron and glass? Since naturally you might tilt you head slightly into the cheek rest
But could be a defect? Cant fully understand or know without a picture. Of anything call the manufacturer

From the operator manual:
6. Operation of Close Range Engagement Sights
a. The ACOG’s Back-up Iron Sights work in daylight or dark. In daylight, the
backup sight is used by aligning the top of the front sight on the target in the
center of the rear sight ring. In darkness align the green dot just below the
center of the target which should be center in the rear sight.

b. The Back Up Iron Sights (BUIS) are factory zeroed for 50 meters and are on
again at 250 meters. The BUIS close range zero can be shortened by putting
shim washers under the rear sight. Windage is adjusted by drifting the front
sight right or left. The bullet will move in the opposite direction as the
movement of front sight.

Every one iíve seen is like that, including the two I own. Iíve asked the same question for years, but never got a square answer other than to drift the sight with a punch and hammer. . The buis arenít zeroed for 50 meters for windage. Youíll miss the target completely. Try it and youíll see. The front sight is drift adjustable but i never bothered. Itís a great scope though. Enjoy.
