ZEROING YOUR SIGHTS…

4. Check that your field of fire is clear, and that it is safe to shoot. Carefully aim and fire a group of three

shots at the center of the target bullseye.

Inspect your target - if your shot group is not in the center of the bullseye, the squares on the target sheet

will help you calculate the required “clicks” necessary to move your next shot group toward the bullseye.

(Remember! -

any changes in elevation are to be made by moving Front Sight Post only.)

If you need to raise your next shot group to get closer to the

bullseye, rotate the Front Sight Post clockwise one click. A Front

Sight Adjustment Tool (Part# RAY-005 - see Bushmaster Catalog

or Website) is recommended for this but not necessary – the sight

can be adjusted with the tip of a Bullet as shown at right. One click

will move the the bullet strike point one vertical square on the

target sheet. If you need to lower your next shot group, rotate the

Front Sight Post counterclockwise. (One click - as before - equals

one square.) Changes in Windage are made with the Windage

Knob. (Three clicks will move the strike point of the Bullet one

horizontal square on the target

sheet.) To move the shot group to

the left, turn the Windage Knob counterclockwise. To move the

shot group to the right, turn the Windage Knob clockwise.

Carefully aim and fire another group at the center of the target

bullseye. Repeat Steps 6 and 7 as required to get your shot groups

into the bullseye.

Once your shot group is on target, your Sights are zeroed, or “calibrated”. To set your Rifle’s sights to a

300 meter zero, rotate the Elevation Knob one click “down” (2 clicks for the A3 Sight). The Range

Scale’s 300-meter mark should now be aligned with the corresponding mark on the Receiver.)
