Iron Sight Adjustment

Those ThunderHawks equipped with the rear sight as shown in figure 1 below are adjustable for elevation by sliding the elevation blade up to raise the point of impact and down to lower the shot's impact.

Rear Sight Elevation Adjustment Screw

It is necessary to loosen the elevation lock screw (by turning it counterclockwise, as viewed from the rear) before sliding the sight blade to the desired setting. To adjust the windage it is necessary to move the entire rear sight leaf left or right by using the slotted screw head on the right side of the rear sight (as viewed from the receiver end of the sight). Move the rear sight blade in the direction you want your shots to hit-- (Example; Turn the screw clockwise -thereby moving the sight blade to the right, to move your shots to the right and counter-clockwise to move the shots to the left).

On ThunderHawk "Shadows" equipped with a rear sight as shown below:

If any adjustment is needed: turn the Windage Adjustment Screw clockwise as viewed in the diagram here to make your shots hit further to the right. Counterclockwise to make them hit to the left. Turn the Elevation Adjustment Screw clockwise as viewed from the front to raise your shots and counterclockwise to lower them.
