Introduction
Why Bore Sighting Matters
The journey to shooting accuracy with your AR-15 begins long before your first shot downrange. While the thrill of pulling the trigger and the satisfying *thwack* of a hit are undoubtedly enjoyable, achieving consistent accuracy requires a systematic approach. One of the most critical steps in this process, often overlooked by new shooters, is **bore sighting**. This guide will provide you with a thorough understanding of **bore sighting your AR-15**, demystifying the process and equipping you with the knowledge to zero your rifle with confidence, saving you time, ammunition, and the frustration of chasing shots down the range.
The Significance of Proper Alignment
The foundation of accuracy starts with proper alignment, and that’s precisely where bore sighting shines. Think of it as the initial coarse adjustment for your scope or iron sights. It’s a crucial first step, ensuring that your rifle’s barrel, and consequently, the bullet’s trajectory, is reasonably aligned with your aiming device. Without this essential step, you might find yourself burning through a mountain of ammunition, desperately trying to get your shots on target, or even worse, completely missing the target entirely.
The Goal: Efficient Zeroing
The primary aim of bore sighting is straightforward: to get the barrel and the scope or sights on your AR-15 roughly pointing in the same direction. This initial alignment significantly reduces the amount of adjustment needed at the range. Essentially, it gets you “on paper” with your shots much faster, allowing you to fine-tune your zero and achieve the desired point of impact with greater efficiency. It’s about making your zeroing experience smoother, more efficient, and more enjoyable.
Understanding Bore Sighting
The Core Definition
What you need to properly **bore sight your AR-15** extends beyond just the rifle itself. Let’s explore the essential tools and equipment that will set you up for success.
Essential Equipment and Tools
You’ll need dedicated tools to get the job done. These include the various types of tools used for bore sighting, and choosing the right one can depend on your budget and preference. There are different options for performing this important task, each with its own set of advantages.
Laser Bore Sighters: An Explanation
One common approach involves a laser bore sighter. These devices, typically chambered to fit your AR-15’s caliber, emit a laser beam down the barrel. This beam projects a small red dot onto the target, allowing you to align your scope’s reticle with the laser’s point of impact. They are relatively inexpensive, portable, and easy to use. However, be aware that the laser can sometimes be slightly off, and their accuracy can vary depending on the quality of the device. It’s also crucial to select the appropriate chamber adapter for the caliber of your AR-15 to ensure proper fit and function. If you find your rifle is not grouping well during zeroing, consider re-verifying your laser bore sighter alignment.
Optical Bore Sighters: Details
Another option is an optical bore sighter. These tools typically attach to the muzzle or chamber and allow you to look through a small scope that is designed to align with the bore. By viewing the target through the bore sighter, you can adjust your scope’s windage and elevation until the reticle in your scope aligns with the target. Optical bore sighters can be more precise than laser versions. This precision is due to the direct visual connection to the bore. They also don’t rely on batteries, which ensures they will be functional when you are ready to zero. While potentially more accurate, they can sometimes be more time-consuming to use, as you must carefully align the bore sighter with the bore itself.
Traditional Methods and Cleaning Rod Technique
A more traditional, and certainly inexpensive, technique involves using a cleaning rod and a target with a grid pattern. With the rifle securely mounted, you can look down the bore and note where it points on the target. This will require some experience and a keen eye.
Other Necessary Items
To make sure you get a good result, you also need a few other items. Ensure you have your AR-15 rifle itself, obviously, with your scope or sights already mounted. A stable shooting position is a must. This could be a bench rest, a sturdy tripod, or any other platform that allows you to hold the rifle steady. Targets are also a requirement. Look for targets with a grid pattern; these will aid greatly in making accurate adjustments. Don’t forget to wear appropriate hearing and eye protection. Safety glasses and ear protection are non-negotiable when handling firearms.
Step-by-Step Procedure
Prioritizing Safety
With the tools and equipment assembled, you’re ready to begin the bore sighting process. Let’s break it down step by step.
Before you touch any of your equipment, remember that safety is paramount. Always handle your AR-15 as if it were loaded. Keep the muzzle pointed in a safe direction. Before starting, completely unload the rifle. Visually and physically inspect the chamber and magazine well to ensure there are no rounds present.
Preparing Your Rifle
The next step involves properly preparing your rifle. Secure your AR-15 in a stable position. If you are using a bench rest, make sure the rifle is snug and won’t move during the process. A level surface is helpful. This will help minimize any movement and ensure accuracy.
Using a Laser Bore Sighter
If you’re using a laser bore sighter, the procedure is generally straightforward. First, insert the appropriate chamber adapter into the chamber. Turn on the laser and observe the dot projected on your target. Then, carefully adjust the windage and elevation knobs on your scope or sights until the reticle (the crosshairs or aiming point) aligns with the red dot on the target. This process will get you well on the way to having your sights properly aligned.
Using an Optical Bore Sighter
With an optical bore sighter, the steps are different. With the rifle secured, you’ll insert the bore sighter into the muzzle (or chamber, depending on the type). Then, looking through the bore sighter’s scope, identify the target. Carefully align the bore sighter’s crosshairs with a specific point on the target, like the center of a bullseye or a clearly defined grid line. Now, without touching the bore sighter, adjust the windage and elevation dials on your AR-15’s scope until the scope’s reticle aligns with the same point on the target that you identified with the bore sighter.
The Cleaning Rod Method
If you are using the cleaning rod method, ensure the rifle is secured. Insert the cleaning rod down the barrel. Where the cleaning rod intersects with the target, this is an indication of the barrel’s orientation. Align your scope with this point.
Zeroing at the Range
Making the First Shots
Once you have finished **bore sighting your AR-15**, you’re ready to move to the range and begin zeroing. Here’s a breakdown of what to expect.
After the initial **bore sighting**, it’s time to hit the range. Start by firing a three-to-five shot group at your target at the desired zeroing distance (typically 50 or 100 yards, depending on your intended use and caliber).
Analyzing the Impact
Carefully analyze your shot group. Observe the point of impact (POI) relative to your point of aim (POA). Is your group high, low, to the left, or to the right? This information is crucial for making the necessary adjustments to your scope or sights.
Making Adjustments
Based on your POI, adjust your scope’s windage and elevation. If your shots are hitting low, adjust the elevation dial to *increase* elevation. If your shots are hitting high, adjust the elevation dial to *decrease* elevation. If your shots are hitting to the left, adjust the windage dial to move the point of impact to the right. If your shots are hitting to the right, adjust the windage dial to move the point of impact to the left. Most scopes have markings on the adjustment dials indicating the direction of movement for windage and elevation; be sure to consult your scope’s manual for specific instructions. Make small, incremental adjustments and fire another group of shots to see the impact of your changes.
Fine-Tuning for Accuracy
Fine-tuning is key. Continue making small adjustments to your scope’s windage and elevation until your shots consistently hit the desired point of impact. This might require a few trips back and forth between the firing line and your target. It’s a process of gradual refinement, but the results are worth the effort.
Troubleshooting Common Issues
Laser Bore Sighter Problems
Even with careful bore sighting, you might encounter some challenges. Troubleshooting is a vital part of the process, and here are some common issues and how to address them.
If you are having issues with a laser bore sighter, there are a few common issues. Make sure the batteries are fresh and the laser is working properly. The laser might be loose in the chamber adapter, causing inaccurate alignment. The laser bore sighter might also not be well aligned with the bore. If the laser is consistently off, consider using another method.
Optical Bore Sighter Issues
If you’re using an optical bore sighter, ensure the bore sighter is securely attached and correctly aligned with the bore. Look through the scope and make certain that you can see the target clearly.
