Bore Sighting and Zeroing

Bore sighting is a good preliminary procedure in achieving proper alignment of your sight to the ﬁrearm. If the sight is to be mounted to a Weaver-style rail, it is imperative that the base be parallel to the bore. Any major elevation adjustments may be accomplished by shimming the Weaver-style rail. It is important not to use the elevation adjustment of the sight for major adjustments. The sight’s elevation and windage adjustments should be used only for ﬁne-tuning to achieve zero at the desired shooting distance. Final zeroing of your ﬁrearm and sight should be done with live ammunition.

WINDAGE AND ELEVATION ADJUSTMENTS

The Bushnell® Holosight® XLP has rotating adjustment features for elevation and windage adjustments. The feature at the back of the sight is the elevation adjustment and the feature at the front side of the sight is the windage adjustment. Both of the adjustment features have a slotted head that requires the use of a screwdriver, coin, or similar tool to rotate.

The elevation and windage adjustments are shown in Figure 5. For both elevation and windage, each click will change the bullet’s point of impact 1/2 Minute of Angle (MOA), which translates to 1/4 inch at 50 yards, 1/2 inch at 100 yards. Also, one full rotation of either knob will change your point of impact 15 MOA. This translates into 8 inches at 50 yards, 15 inches at 100 yards. To move the point of impact UP, turn the adjustment counterclockwise; to move the point of impact DOWN, turn the adjustment screw clockwise. To move the point of impact RIGHT, turn the adjustment screw counterclockwise; to move the point of impact LEFT, turn the adjustment screw clockwise. The elevation and windage adjustments have been initially set at the factory near the midpoint of their adjustment ranges as well as parallel to the rail, and should be close to zero with a properly installed sight and mounting rail. Do not

make adjustments before mounting the sight on the ﬁrearm. Be sure to check that the mount and the sight remain fully secured after the ﬁrst 2 to 3 shots.

CAUTION-When a sudden increase in resistance in the adjustment screw is felt, the end of the adjustment range has been reached. DO NOT try to turn the adjustments any further or damage may occur to the sight.
