How to Bore Sight a Scope Without Laser Bore Sighting Tools: A Professional Guide

Bore sighting a scope is essential for any shooter to ensure accuracy while shooting. Bore sighting is the process of aligning the scope with the barrel of the rifle. It is the first step before zeroing in on the target. While laser bore sighting tools are available in the market, not everyone has access to them.

Fortunately, bore sighting can be done without laser bore sighting tools.

There are several methods for bore sighting a scope without laser bore sighting tools. One method is to use a bore sighter, which can be inserted into the muzzle of the rifle.

Another method is to remove the bolt and look down the bore of the rifle to center it on the target. Once the bore is centered on the target, the scope can be adjusted to align with the bore. This can be done by adjusting the windage and elevation of the scope until the reticle is centered on the target.

Another method is to use a laser pointer. This is a cheap alternative to laser bore sighting tools. The laser pointer can be inserted into the muzzle of the rifle, and the beam can be aligned with the center of the target.

Once the laser is aligned with the target, the scope can be adjusted to align with the laser. This can be done by adjusting the windage and elevation of the scope until the reticle is centered on the laser dot.

Understanding Bore Sighting and Its Importance

Bore sighting is the process of aligning the bore or center of the barrel of a rifle with the sights or scope on the firearm. It is an essential step in the zeroing process and ensures that the point of impact matches the point of aim.

Bore sighting is crucial for accuracy and should be done before sighting the rifle. It helps to reduce the number of shots required to zero the rifle and saves both time and ammunition. Bore sighting is also useful for ensuring that the scope is mounted correctly and is aligned with the barrel.

A sighting system is only as good as its zeroing. Zeroing a rifle means adjusting the sights or scope so that the point of impact matches the point of aim. Bore sighting helps to get the rifle on paper and reduces the number of adjustments required to achieve a proper zero.

There are several methods of bore sighting, including using a laser bore sighter, bore sighting collimator, or even a simple bore sighting tool. However, in the absence of these tools, bore sighting can still be done using a few simple steps.

First, ensure that the rifle is unloaded and remove the bolt. Next, look down the barrel and align it with an object at a distance of around 25 yards. Then, adjust the rifle until the object is centered in the bore. Finally, look through the scope and adjust it until the crosshairs are aligned with the object in the bore.

Bore sighting is an essential step in the zeroing process and helps to ensure accuracy and consistency. While there are several tools available for bore sighting, it can still be done using simple methods. It is important to note that bore sighting should always be done in a safe and controlled environment.

Selecting the Right Equipment

When it comes to bore sighting a scope without laser bore sighting tools, selecting the right equipment is critical. The equipment required will depend on the type of firearm being used, as well as the type of scope and ammunition.

For rifles, both bolt-action and semi-automatic, the first step is to remove the bolt from the rifle. This will allow the user to look down the bore of the rifle and align it with the target. For pistols, the user can remove the slide to access the barrel and perform the same procedure.

Next, the user will need a stable platform to rest the firearm on. A table with sandbags or a rifle rest will work well. This will ensure that the firearm remains stable and does not move during the bore sighting process.

The user will also need a target to aim at. A target with a black bullseye will work well, as it provides a clear point of aim. The user can also use a piece of paper or cardboard with a small dot in the center.

Finally, it is important to have a metal rod or bore sighter to help align the scope with the bore of the firearm. This will ensure that the point of aim and point of impact are aligned.

When selecting a metal rod or bore sighter, it is important to choose one that is the correct size for the firearm being used. The user can measure the diameter of the bore using a caliper or consult the manufacturer’s specifications.

By selecting the right equipment, the user can ensure that the bore sighting process is accurate and effective.

Preparing Your Rifle for Bore Sighting

Before bore sighting a rifle scope, it is important to ensure that the rifle is properly mounted and secured. A loose or improperly mounted scope can lead to inaccurate bore sighting results, which can have serious consequences when firing live rounds.

To prepare the rifle for bore sighting, the shooter should first ensure that the scope is properly mounted on the rifle. This includes ensuring that the scope rings are properly tightened and that the scope is level and aligned with the rifle’s bore. A leveling kit can be used to ensure that the scope is properly aligned.

Next, the shooter should ensure that the rifle is properly secured in a stable shooting position. This can be done by using a rifle rest or sandbags to support the rifle and prevent it from moving during the bore sighting process.

If bore sighting a bolt-action rifle, the shooter should remove the bolt from the rifle and set it aside. This will prevent the bolt from interfering with the bore sighting process and ensure that the rifle is properly aligned with the bore.

For rifles with an upper receiver, the shooter should remove the upper receiver from the lower receiver and secure it in a rifle rest or vise. This will provide a stable platform for the bore sighting process and ensure that the rifle is properly aligned with the bore.

By properly preparing the rifle for bore sighting, the shooter can ensure that the bore sighting process is accurate and reliable. This will save time and frustration when zeroing in the rifle scope with live rounds.

Steps to Bore Sight a Scope Without a Laser

Bore sighting a scope without a laser can be a challenging task for a beginner. However, with the right steps and techniques, it can be done successfully. Here are the steps to bore sight a scope without a laser:

Positioning the Rifle

Firstly, the rifle must be positioned on a solid mounting system. This can be done using a professional, solid rest or by improvising with sandbags or pillows. The rifle must be placed in a stable position to ensure that the sighting process is accurate and effective.

Aligning the Bore and Scope

Once the rifle is positioned, the bore and scope must be aligned. This can be done by removing the bolt from the rifle and looking down the bore. The bore must be aligned with the center of the target. Once this is done, the rifle must be placed back in the rest and the scope must be adjusted to align with the bore.

Adjusting the Windage and Elevation

After aligning the bore and scope, the windage and elevation must be adjusted to center the point of aim. The windage turret must be adjusted to move the reticle left or right, depending on where it is about the bullseye. Similarly, the elevation turret must be adjusted to move the reticle up or down, depending on where it is about the bullseye.

It is important to note that the windage and elevation adjustments must be made in small increments to ensure accuracy. Once the adjustments are made, the rifle must be fired to confirm the zero. If the point of impact is not at the center of the target, the adjustments must be made again until the zero is achieved.

Bore sighting a scope without a laser can be done successfully with the right steps and techniques. By positioning the rifle on a solid mounting system, aligning the bore and scope, and adjusting the windage and elevation, the point of aim can be centered accurately.

Testing and Adjusting the Sighting
