Sight Alignment

Optional Sighting-In Techniques

Use bore or collimator sighting-in initially to line up the rifle on the paper target. However, these techniques alone are not sufficient to sight-in a rifle. You must make final adjustments by shooting the rifle with the same ammunition you plan to use in the field.

• Bore sighting-in with bolt-action rifles: Remove the bolt, brace the firearm on sandbags, and look directly through the bore. Correct the rifle's position until you see the bull's-eye in the center of the bore. Adjust the sights to give you a good sight picture.
• Collimator sighting-in for rifles without bolt actions: A collimator slips into the muzzle end of the barrel and allows you to adjust sights much like bore sighting-in.
