HOW TO BORE SIGHT A SCOPE-MOUNTED RIFLE OR HANDGUN
Scope/Rie Combination
Once you have secured the Boresighter, place the rie on a suitable support. Remove the
adjustment caps from your riescope. Then sight through the riescope and align the reticle
with the crosshairs of the graduated grid reticle in the Boresighter by using the riescope’s
elevation and windage adjustments. Once you have aligned the riescope reticle with the
graduated grid reticle in the Boresighter, you are ready for sighting-in on the range. If bore
sighting has been done properly, sighting-in should take a minimum of time and ammunition.
HOW TO INSERT THE EXPANDABLE ARBOR INTO THE GUN BARREL
Place the gun with mounted scope into a suitable support. Select the proper arbor and make
sure the expandable tips are completely closed by turning the arbor’s locking nut (Fig. 1/2: A)
counter-clockwise until the tips contract. Insert the small end of the arbor into the Boresighter
mount with the at area down, so that the end of the clamp screw (Fig. 1/2: B) will bear against
the at surface. Turn the screw clockwise until it is ngertight. Now, with the Boresighter in an
upright position, insert the arbor into the barrel and push it forward carefully until the muzzle
rests against the tapered section of the arbor (Fig. 2) ). With the arbor locking nut loosened,
and while looking through the scope, swing the Boresighter to align vertical grid lines with
the scope reticle. Turn the arbor locking nut clockwise until the arbor holds rmly to the bore;
the expandable tips prevent the Boresighter from turning of its own weight.
NOTE: To remove the arbor from the barrel, simply loosen the arbor locking nut (Fig 1: A),
push inward to retract the tips, and pull the unit from the barrel.
