 for this purpose (fig 18). Lateral zeroing is done by moving the cylindrical front sight post mount from side to side using the lateral zeroing tool (fig 19).

If the strike of the bullet is below the control point, the front sight should be screwed in. If above, it should be screwed out. If the strike of the bullet is to the left of the control point, the slide of the front sight should be moved to the left; if to the right, to the right.

Moving the front sight slide to the left, right, up or down 1mm, changes the strike of the bullet 26cm at 100 meters. One full turn on the front sight post moves the strike of the bullet 20cm when firing at 100 meters. Front sight post changes should be verified by a group of four individually aimed shots. After the weapon has been zeroed, the old mark should be removed and a new one written in.
