Understanding Laser Bore Sighters
Different Types of Laser Bore Sighters
The market offers a range of laser bore sighters, each designed to cater to specific firearms and preferences. Familiarizing yourself with the most common types will help you choose the one that best suits your needs.
One prevalent type is the cartridge-based laser bore sighter. These units mimic the dimensions of actual ammunition and are specifically designed to fit into the chamber of your firearm. They are available in a wide array of calibers, accommodating various rifles and handguns. To use this type, you simply insert the laser bore sighter, much like you would load a live round. The laser then emits a beam that allows you to align your sights or scope.
Alternatively, muzzle-mounted or magnetic laser bore sighters offer another approach. These are typically designed to attach to the muzzle of your firearm using magnets or other attachment mechanisms. This method offers versatility as it doesn’t require chamber compatibility. The beam is then projected down the barrel, much like a cartridge-based sighter, guiding your adjustments.
Components and Their Purpose
A laser bore sighter is a relatively simple device, composed of a few key components working together. The heart of the system is, of course, the laser emitter. This component houses the laser diode, which generates the focused light beam. The laser’s accuracy and brightness are important factors in determining its overall effectiveness.
A battery compartment is essential. The laser is powered by batteries, usually small lithium cells, to ensure the laser is working correctly. The location of the battery compartment varies depending on the type of bore sighter.
The on/off switch is your control point. This allows you to activate and deactivate the laser, conserving battery life and preventing accidental emissions.
Often, a laser bore sighter will include accessories like adapters or bore guides. These tools often help to ensure that the laser sits properly within the barrel or chamber, providing a more accurate alignment.
Safety First: A Crucial Reminder
Before we proceed, it is absolutely paramount to reiterate the importance of firearms safety. The following safety measures *must* be observed throughout the entire process:
Always Treat the Firearm as Loaded: Even if you are certain it is unloaded, never handle a firearm casually. This principle applies at all times.
Point in a Safe Direction: Always direct the muzzle in a safe direction. If you are in a shooting range, point the muzzle at the target.
Verify Unloaded Condition: Before working with the firearm, *always* confirm that the chamber is empty. Open the action and physically inspect the chamber and magazine to ensure no ammunition is present.
Eye Protection is Essential: Wear appropriate eye protection to prevent any potential injury from reflected light or debris.
With these vital safety precautions in mind, let’s proceed to the step-by-step instructions.
Step-by-Step Guide on Using a Laser Bore Sighter
Preparing Your Firearm and Workspace
The foundation of a successful laser bore sighting is careful preparation. Begin by ensuring your firearm is unloaded. Remove the magazine, open the action (bolt, slide, etc.), and physically inspect the chamber to confirm it is empty. Place the firearm in a stable rest. Using a shooting rest or a gun vise is essential for maintaining a stationary position during the entire process. This will prevent any unintended movement during adjustments.
Choose a well-lit workspace. Adequate lighting allows you to clearly see the laser dot on the target and accurately make adjustments to your sights or scope. Ensure that there is sufficient distance to the target for the firearm you are working with. Generally, 25-50 yards (meters work too) is ideal for rifles, while shorter distances may be sufficient for handguns.
Installing the Laser Bore Sighter: A Specific Guide
The installation process varies slightly depending on the type of laser bore sighter you are using. Here’s a detailed breakdown:
Cartridge-Based Installation
First, install the appropriate batteries. Choose the correct batteries for your model of laser bore sighter. Once you have the correct batteries, carefully insert them into the compartment, ensuring they are correctly oriented according to the instructions.
Select the correct caliber adapter (if required). Some laser bore sighters come with interchangeable adapters to fit different calibers. If your laser bore sighter has an adapter, select the one that matches your firearm’s caliber.
Next, gently insert the laser bore sighter into the chamber, much as you would insert a live round. Make sure it seats correctly and is aligned with the bore. Close the action (if possible). If the action cannot fully close due to the laser, this is perfectly normal.
Muzzle-Mounted Installation
Begin by installing the required batteries. Then, carefully attach the laser bore sighter to the muzzle of your firearm. Follow the manufacturer’s directions. Make sure the laser is centered in the bore to guarantee a true alignment. Ensure the attachment is secure to prevent the bore sighter from shifting during adjustments.
Aiming the Laser: Finding the Point
Activate the laser bore sighter. Once your laser bore sighter is installed and switched on, the laser will project a visible dot. Look downrange at your chosen target. Keep in mind the appropriate distance (mentioned before). You will see a small, red dot on the target. This dot represents the point where your firearm’s bore is currently aligned.
Adjusting Your Sights or Scope: Precision at Your Fingertips
The next step is to align your sights or scope with the laser dot. Without moving the firearm, which is held securely by the rest, observe your sights or scope.
Make adjustments to your sight or scope for windage (left/right) and elevation (up/down) until the crosshairs (or reticle) align with the laser dot on the target. Remember to be methodical; small, precise adjustments are key.
Most scopes have adjustment knobs that are marked with MOA (Minute of Angle) or click values. Understanding these adjustments is essential for precision. One MOA represents roughly one inch at 100 yards. Each click on the adjustment knob will move the point of impact by a specific amount. Consult the owner’s manual for your scope to understand the click value. As you continue to practice, you will naturally become more familiar with these adjustments.
Live Fire: The Confirmation Phase
After the sighting process, carefully remove the laser bore sighter. Load the firearm with the ammunition you intend to use. Fire a group of shots at your target. Note where your shots impact relative to the point of aim, and further adjust your scope or sights based on the group’s position. Remember this is to ensure the actual point of impact aligns with your aiming point. It is completely normal to need further adjustment after your initial live fire.
Removing the Bore Sighter and Proper Storage
After completing the zeroing process, take time to properly remove the bore sighter from your firearm. Switch off the laser, and if the bore sighter uses removable batteries, take them out. Store the bore sighter in a safe, dry place. Keeping the batteries out will help preserve the life of the bore sighter.
Troubleshooting
Addressing Potential Issues
Even with careful adherence to the steps, you might encounter some difficulties. Here are some common problems and how to address them:
If the laser dot appears off-center on the target, re-examine the installation. Make sure the bore sighter is properly seated and secure in the chamber or on the muzzle. Clean the barrel if it’s dirty as this could affect alignment.
Inconsistent results can be frustrating. Ensure the firearm is held securely during both the adjustment and live-fire stages. Verify the bore sighter’s batteries. Then review the distance and target conditions.
If the laser isn’t working, confirm the batteries have sufficient charge, that they’re inserted correctly, and that the unit is turned on. There may be a faulty component in the bore sighter, which is more common in cheaper models.
