Safety is Paramount
The responsible handling of firearms is non-negotiable. Before embarking on the journey of how to adjust a gun scope, a thorough understanding of firearm safety is essential. Always prioritize safety above all else.
Always check to make sure your firearm is unloaded before you begin any work. Never assume a firearm is unloaded. Always perform a visual and physical inspection of the chamber and magazine well to confirm the absence of ammunition. Remove the magazine, if present, and cycle the action several times, ensuring no round is present in the chamber. Once cleared, the firearm can be safely examined.
Always point the muzzle in a safe direction. Be aware of the target and what’s beyond it. Consider what could happen if your shot misses, and avoid shooting towards areas where people or property could be harmed. Always be mindful of the surroundings and ensure a safe backstop is in place to contain any stray rounds.
Furthermore, always use appropriate eye and ear protection. Shooting can be loud and dangerous to your eyesight and hearing. Ensure you have both eye and ear protection to prevent injury. These simple steps are essential for keeping yourself and those around you safe.
Familiarize yourself with the basic firearm safety rules. Handle the weapon as if it is always loaded. Never point the muzzle at anything you are not willing to destroy. Keep your finger off the trigger until you are ready to shoot. Always be certain of your target and what is beyond it.
Understanding the Scope’s Components
Before we delve into the practical aspects of how to adjust a gun scope, it’s crucial to understand the anatomy of your optical device. Knowing the function of each component is key to understanding how adjustments affect your point of impact.
The objective lens is the large lens at the front of the scope. This lens gathers light and directs it into the scope, providing the image you see. The quality of the objective lens greatly affects the clarity and brightness of the image.
The eyepiece is the lens you look through. It magnifies the image from the objective lens and provides the view you use to aim.
Many scopes feature a magnification ring, allowing you to adjust the power of the scope. This lets you zoom in on your target for a closer view. Different shooting situations may benefit from different magnifications.
The windage and elevation turrets are where the magic happens when learning how to adjust a gun scope. These are the dials you turn to correct for wind drift and bullet drop. The windage turret is on the side and adjusts horizontal aim, while the elevation turret is on top and adjusts vertical aim. Each click of these turrets moves the reticle (the aiming point) a specific amount, typically measured in minutes of angle (MOA) or milliradians (MRAD).
The reticle is the aiming point within the scope. It can take various forms, such as a crosshair, a dot, or a complex pattern. The reticle helps you align your sights with the target. The choice of reticle is often a personal preference, depending on the style of shooting.
Some scopes include a parallax adjustment. Parallax is the apparent movement of the reticle relative to the target when your eye isn’t perfectly aligned with the scope. This adjustment ensures the image is in perfect focus at a specific distance.
Choosing Your Supplies and Preparation
Now that you have a good grasp of the basics of the device, and the important rules of safety, it’s time to gather everything needed for the task of how to adjust a gun scope.
You’ll need your firearm, along with the scope attached. Ensure the scope is securely mounted. Make sure you have the correct ammunition for your firearm, the right round type, and any specialized equipment.
A suitable target is also essential. Choose a target designed for sighting in scopes, with clearly marked aiming points. It helps if the target has some sort of grid pattern or markings.
A stable shooting platform is crucial for accurate adjustments. Consider using a bench rest, a bipod, sandbags, or any device that provides a steady base for your firearm. This will eliminate any human error due to shaky hands.
Having the right tools is also important. You may need a screwdriver or Allen wrench to make adjustments to the scope mounts or the scope itself.
Choose a safe range at which to shoot. This will depend on the caliber of your weapon and the distance at which you are zeroing the scope. Check the range’s regulations and make sure it’s suitable for sighting in.
With all of your equipment gathered, the most important step is to ensure that your firearm is ready to be used, safely. Remember to follow the safety protocols previously mentioned.
The Sighting Process: Steps to Precision
Finally, let’s delve into the practical techniques of how to adjust a gun scope to achieve the perfect zero. Here’s a detailed step-by-step guide to walk you through the process.
The first phase is generally called “Bore Sighting.” Its aim is to roughly align the scope with the barrel’s bore, minimizing the initial adjustment needed when live firing.
If you don’t have a dedicated bore-sighting tool, or an optical bore sighter, you can still do a reasonable job. First, make sure your firearm is completely unloaded and the action is open. Place your rifle on a stable rest, ensuring the firearm is securely held. Now, visually align the bore of the barrel with a target, if possible, at a reasonable distance, such as 50 or 100 yards. Focus on a specific point on the target. Without moving the rifle, look through the scope. Adjust the windage and elevation turrets to bring the reticle onto the same aiming point you chose. This is a rough process, but it drastically reduces the amount of adjustment you’ll need when you live-fire.
Now, it’s time to move onto live fire, and begin your zeroing process. Load the firearm with the correct ammunition. Place the firearm on a solid platform, and prepare to fire. Take several shots, usually a group of three or five shots, to determine the point of impact. Analyze the grouping. Where the shots land in relation to your point of aim is critical.
Now it’s time to begin how to adjust a gun scope based on the results of your shots. If your shots are hitting to the right and low, you need to adjust the scope. Most scopes have turrets marked with “up” or “down,” and “left” or “right,” which may be different based on the brand or design. It’s crucial to understand the labeling to get accurate results. If you are using a scope measured in MOA, each click of the turret typically moves the reticle ¼ inch at 100 yards. If the scope is in MRAD, each click is 0.1 MRAD.
Once you have determined how the results of your shots compare with your point of aim, begin making the required adjustments to the turrets. Remember to turn the turrets in the direction that will move the reticle toward the point of impact. Turn the elevation turret to raise the point of impact, and the windage turret to move the impact to the left or right. Once the appropriate adjustments are made, fire another group.
After firing another grouping of shots, repeat the adjustment process until the bullets are hitting where you aim. The objective is to have the reticle aligned with the point of impact at the desired zero distance.
Once your shots consistently hit the target at your zero distance, you’ve successfully sighted in your scope. You can now make fine-tuning adjustments if desired. Check your results by shooting several more groups to ensure accuracy.
Troubleshooting Common Issues Encountered During Sighting
While mastering how to adjust a gun scope is not difficult, sometimes problems can arise during the process. Here are some of the most common difficulties that you may face, and how to overcome them.
Sometimes, the turrets on a scope can be sticky and not adjust easily. This could be due to a variety of factors, such as the age of the scope, lack of lubrication, or damage. If this occurs, it is worth investigating, so as to prevent the problem from worsening.
One of the most frustrating problems is a “walking zero.” This is where the point of impact slowly shifts with each shot. If your point of impact is shifting around, it could be caused by several problems: a loose scope mount, improper mounting of the scope, or a problem with the internal components of the scope. To solve this, always check the scope mounting. Verify that all screws are tight and properly installed. You may also consider having the scope examined by a professional.
You may experience a reticle that isn’t centered, or otherwise seems out of alignment. Sometimes this is obvious, and other times it is more subtle. It’s important to always ensure the scope is correctly mounted and that the reticle is correctly aligned.
Long-Term Maintenance and Practice for Success
The job of how to adjust a gun scope doesn’t stop once you have a good zero. It’s important to maintain your scope and continue practicing to ensure continued accuracy.
Regularly clean your scope lenses with a soft cloth to remove dust, dirt, and fingerprints. Consider using lens-cleaning solutions. It is important to avoid harsh chemicals.
Periodically inspect your scope mounts and bases. Make sure that all screws are tight, and the mount itself is in good condition.
Consider using a scope cover. It can protect your scope from the elements and impacts. Store your rifle in a safe, protected place.
Finally, practice is essential for consistently achieving excellent results. The more you practice, the better you will understand the nuances of your equipment and your personal shooting style.
