right
Front sight move in opposite direction and rear sight move in the same direction to change the POI
( point of impact) . ..If you want to move the POI down you move the front sight up or the rear sight down

Yup. Front site moves thesame direction as where your shots are hitting - ie: if they hit right of your aiming point, move the fornt to the right.
Rear sights move opposite - hitting right of point of aim, move rear left. Vertical is the same - if it's shooting high, Rear goes down and front goes up.

Now if you get the front post all the way over to the right and you are STILL hitting right of POA.
Your barrel may not be fully indexed in the receiver or your flash suppresor (and front sight) may be off center (as mine was).
You can counter this by moving your rear sight aperture (windage knob)a couple clicks to the left until you are bang on at 100m.
Or you can get someone to index the barrel.

Sounds like you have an out of index flash hider like mine and the front has to be to the right edge of the sight ramp. I believe they knew the batch was wrong at the sweet and sour factory, because mine was even staked at the factory, all the way right.
Guess you could call it post active QA.
Don't dump the 30,000 Flash hider's the kid screwed up on by not checking the first one coming of the lathe, just measure the out of index, and then determine the precise movement of the front sight to give a vertical zero , and then "STAKE" it there.
Wish the guy who figured this out was around to check the first screwed up one, and then set up the guys machine for him.
I remember a post by M-14 doctor sharing that alot of the 2009 and later barrels were not out of index, but the flash hiders were cut," out of".
