I am not sure what sort of front sight you guys have but the elevation and windage adjustments on mine are achieved simply by twisting the sight post.
You see, the posts are made to lean to one side a bit so if you turn them 360* you will go through all the possible windage options.
If your windage is out that much that twisting the front sight post won't help, just take hammer and a punch and move the horizontal base side to side.
