How to Laser Bore Sight a Bolt and Stop It
Laser bore sight is a simple but effective way of aligning the sight system of your firearm with the bore. The function of a laser bore sight is primarily to facilitate this alignment. The laser sight saves ammunition and time, since it places the sight or scope right within the line of sight without actually firing the gun. Using a laser sight allows you to quickly align the sight with the bore and thus increase accuracy of your firing. This is because using laser sights, it is possible to place the sight at just the exact distance that the bore must be sighted at in order to get the precise result.
To use a laser bore sight, the first step is to zero your gun. You do this by drawing a pinpoint target on your target sheet. Next, you place the crosshairs on the target outline, directly over your shoulder. Your target should be at least 50 yards away from you for ideal results. The closer that the target is, the faster you should be able to draw the trigger, and the further the shot should be reached to compensate for any recoil you experience.
Once you have zeroed the firearm, you can begin to align the sight with the bore. To do this, place the scope in a horizontal position next to the front sight in your firearm vise. Next, look through the top of your firearm vise and along the inside edge of the lower plate. You will see two numbers on the plate; these numbers will correspond to the left and right alignments on your sight. In order to properly align the sight with the bore, make sure you look through the cross hairs in your vise until you are able to easily see them in black and white. When you have this information, you can move on to aligning the sight with the bore.
Place the laser bore sight in line with the cross hairs on the outside edge of the lower plate, making sure that the numbers on the plate match the numbers in your gun’s sights. The gun should not be moved during this process, so set aside about 10 minutes to properly zero the gun. If you have trouble seeing through the scope when the gun is zeroed, you may need to utilize a magnifying lens or binocular to help make it easier to see through the scope.
After you have aligned the laser sight in accordance with the bore, you will be ready to fire. Line up the laser dot on your target with the front sight on your firearm. Your target should be at least ten yards away for optimal results. As you take aim, ensure that the rear of the gun is also at the aiming point.
At the range, you should pull the trigger as far back as possible, while watching for the red dot to slowly rotate upward. When the dot has reached the apex of its rotation, your gun should be loaded. Once you have loaded, place the rear of the trigger on the paper target. You should begin your target shooting immediately, aiming to get a bullseye at any range above 25 yards away.
To provide you with additional accuracy, the laser bore sight will usually include an adjustable windage knob. By loosening this knob, you can adjust the sight to focus on a point that is closer to your eye. For ideal results, you should perform this job after you have already lined up the crosshairs and are waiting for the sight to rotate completely. Remember to always assume that the dot will be at the center of the target at all times, and never adjust the windage knob until the target has been properly centered on the bore.
To complete the task of boresighting, you should slowly back away from the target as far as you can manage. As soon as you have reached a comfortable distance, slowly open the bolt and bring it down again. The key to success is consistency and accuracy, which only comes with experience. As you become more confident with your ability to do this, you may want to invest in an arbor sight or laser reticle. These devices will make the job of boresighting much easier.
