Sightmark Laser Bore Sight Instructions: A Comprehensive Guide
This guide offers comprehensive instructions for using Sightmark laser bore sights․ It covers safety precautions, setup, bore sighting procedures, troubleshooting, and maintenance, ensuring you can accurately sight in your firearms with ease and confidence․
Understanding the Sightmark Laser Bore Sight
The Sightmark laser bore sight offers a practical method for sighting in rifles and pistols․ It projects a laser beam, simulating bullet trajectory, to align the firearm’s scope or sight․ This tool significantly reduces the need for excessive live ammunition during the initial zeroing process․
By inserting the bore sight into the firearm’s barrel or attaching it magnetically, users can quickly identify the point of impact․ Adjusting windage and elevation settings becomes more efficient, saving both time and ammunition․ The Sightmark bore sight is designed for various firearm types, making it a versatile tool․
Types of Sightmark Laser Bore Sights
Sightmark offers various laser bore sights, including universal and in-chamber models, each designed for specific firearm types and calibers, providing versatile sighting solutions for different needs․
Universal Laser Boresights
Universal laser bore sights, such as the Sightmark Triple Duty model, offer a convenient and accurate method for sighting in various firearms․ These models typically attach magnetically to the end of the barrel, projecting a laser dot onto a target․ This allows for easy adjustment of windage and elevation on scopes or sights․
The self-centering arbor ensures proper alignment, preventing metal from entering the barrel․ They are ideal for quick sighting and reduce ammunition waste․ The magnetic attachment allows for use on a variety of firearms, enhancing their versatility and ease of use․
In-Chamber Laser Boresights
In-chamber laser bore sights are designed to be inserted directly into the firearm’s chamber, similar to a live round․ These devices, like the Yukon Sightmark models, offer a precise alignment reference for sighting in scopes and sights․ Their design ensures compatibility with specific calibers, providing a tailored fit for optimal accuracy․
Sightmark in-chamber bore sights feature multiple set screws for secure laser diode locking, ensuring consistent centering․ They are ideal for hunters and shooting enthusiasts․ These bore sights offer a reliable and efficient method for pre-sighting firearms, reducing the need for extensive live-fire adjustments․
Safety Precautions
Prioritize safety when using Sightmark laser bore sights․ Always adhere to firearm safety rules and avoid pointing the laser directly at eyes․ Follow all safety guidelines in the firearm’s manual․
General Firearm Safety
Before handling any firearm or using a Sightmark laser bore sight, thoroughly read and understand your firearm’s manual and all related warnings․ Always treat every firearm as if it is loaded․ Never point the firearm at anything you do not intend to shoot․ Keep your finger off the trigger until you are ready to fire․ Be sure of your target and what is beyond it․ Store firearms securely and separately from ammunition․ Use appropriate ear and eye protection․ Avoid alcohol or drugs when handling firearms․ Regularly inspect your firearm for proper function․ Familiarize yourself with local laws and regulations regarding firearm ownership and use․
Laser Safety
When using a Sightmark laser bore sight, exercise caution to prevent eye injuries․ Never look directly into the laser beam or point it at another person’s eyes․ Laser radiation can cause serious damage․ Avoid prolonged exposure to reflected laser light․ Ensure the laser is operated in a controlled environment, minimizing the risk of accidental exposure․ Store the bore sight in a safe place, away from children and unauthorized users․ If the laser sight appears to be malfunctioning, discontinue use immediately․ Refer to the Sightmark LoPro manual for additional safety guidelines․ Always prioritize safety when using laser devices․
Initial Setup and Battery Installation
Before using your Sightmark laser bore sight, carefully unpack all components․ Consult the included manual for specific battery type and installation instructions․ Ensure the firearm is unloaded and safely secured․ Locate the battery compartment on the bore sight․ Insert the batteries according to the polarity markings (+/-) inside the compartment․ Close the battery compartment securely․ Turn on the bore sight to verify proper battery installation․ If the laser does not activate, double-check battery polarity and ensure the batteries are fresh․ Store any spare batteries in a safe place․ Remember to remove batteries when storing to prevent corrosion․
Bore Sighting Procedure
This section details the bore sighting procedure using a Sightmark laser bore sight․ It includes setting up the target and adjusting windage and elevation for accurate alignment of your firearm’s scope or sights․
Setting Up the Target
Begin by placing a target at a distance of 20-30 yards, ensuring the laser is clearly visible upon it․ The laser point indicates the theoretical point of impact for your firearm․ It’s crucial to have a stable and well-defined target to achieve accurate adjustments․ Ensure the target is securely positioned to prevent movement during the bore sighting process․ A proper setup will lead to more precise adjustments of your scope or sight․ This initial step is vital for effective bore sighting․ Remember to detach the bore sight and turn it off after sighting․
Adjusting Windage and Elevation
After setting up the target and observing the laser point, carefully adjust the windage and elevation knobs on your scope or sight․ The goal is to align the crosshairs with the laser point projected onto the target․ Make small, incremental adjustments, observing the movement of the crosshairs after each adjustment․ This process ensures accuracy and prevents overcorrection․ Continue adjusting until the crosshairs are precisely aligned with the laser point․ This step is crucial for achieving an initial zero, which will then need fine-tuning at the range with live ammunition․ Consistent adjustments lead to successful bore sighting․
Troubleshooting Common Issues
This section addresses common problems encountered while using Sightmark laser bore sights․ Find solutions for issues like an uncentered laser or an obscured laser, ensuring a smooth and accurate bore sighting process․
Laser Not Centered
If the laser appears off-center, it may affect the accuracy of your bore sighting․ Ensure the bore sight is properly seated in the barrel or chamber․ For universal models, check the magnetic base is clean and firmly attached to the muzzle․
With in-chamber models, ensure the set screws locking the laser diode are tight․ Rotate the bore sight on a flat surface․ If the laser point wobbles, the unit may be defective or require adjustment by a qualified technician․ If problems persist, consider contacting Sightmark customer support for assistance․
Obscured Laser
An obscured or half-moon laser indicates an issue with the bore sight or obstruction․ First, ensure the firearm’s barrel is clean and free of debris․ Rotate the bore sight while pointed at a wall; if the obscuration remains consistent, the bore sight itself is faulty․
Check the laser aperture for any dirt or damage․ For in-chamber models, ensure proper seating; avoid forcing it․ If the issue persists, contact Sightmark support․ Avoid disassembling, as it voids the warranty․ A clear laser is crucial for accurate bore sighting․
Maintenance and Storage
Proper maintenance and storage of your Sightmark laser bore sight ensures longevity and accuracy․ After each use, clean the bore sight with a soft, dry cloth to remove any residue․ Avoid using solvents or lubricants, as they can damage the laser diode or electronic components․
Remove the batteries before long-term storage to prevent corrosion․ Store the bore sight in its protective carrying case in a cool, dry place away from direct sunlight and extreme temperatures․ Handle with care to prevent damage to the laser and internal components․
