The Laser Bore Sight is factory aligned for simple installation. Place the batteries into the Bore Sighter housing replace the end cap turning to the right until the end cap lightly seats, this activates the Bore Sight laser. Place the Laser Bore Sighter into the weapons chamber (always maintain laser safety rules), using the correct arbor for the caliber to be sighted. Slowly close the bolt (it may not be necessary to have the bolt closed if the bore sight fits snug in the chamber).
Measure 25 yards, you may use a vice or gun rest to assist in holding your weapon on target. While the laser is on the bull’s eye, you can now observe how many inches your scope or iron sights off target (the laser will put you within 1.5 to 2 inches of dead center). Due to the fact that scopes vary, you must follow instructions for your particular scope to adjust the cross hairs to the bull's eye. It is not necessary to calculate the exact number of clicks. You may simply click the reticule up or down, left or right until it is on the bull's eye. The same procedure is used for iron sights.
Remove the Laser Bore Sight after sighting your weapon (if the bore sight stick in the chamber, a cleaning rod may be used to lightly tap the sight out of the chamber) turn the Bore Sighter end cap to the left turn off the laser.
We recommend removing the batteries from the Laser Bore Sight for storage. A battery discharged in your Bore Sighter could possibly destroy your unit.
Our measurements for laser bore sights are based on S.A.A.M.I specifications.
If after inserting the laser bore sight the bolt cannot be closed, you may sight the weapon with the bolt open. This might be caused by the end switch.
If the impact group of live ammunition shooting is off center after the rifle is zeroed by a newly acquired laser bore sighter (see Fig.1), the axis of the chamber does not coincide with the axis of the barrel on your rifle or the barrel is bent.

You may still use the laser bore sighter to sight by:
Sight your scope and rifle by live bullet firing at a range of 100-150m. Insert the laser bore sight into the chamber. Use the target paper (see Fig. 2) and aim at the center with the range 25-30m away while marking the red dot point of laser boresighter and keeping the record for future use. Later if you want to zero this rifle again, simply aim the laser bore sight point to the red dot point marked and adjust elevation and windage of the scope to coincide the center of crosshair to the zero point on the paper.
