Laser Boresighters for Sight Alignment

Laser boresighters help you align your sights or optics without firing rounds. Our collection includes red and green laser models that insert into your barrel to project a reference point for zeroing scopes, red dots, and iron sights. Each boresighter includes batteries and provides a starting point for zeroing before live fire confirmation.

Red vs Green Laser Boresighter Options

Our laser boresighters come in two laser color options:

  • Green Laser Boresighter: Provides good daytime visibility with a brighter beam that's easier to see in outdoor conditions. The green laser shows up more clearly against most backgrounds and at longer distances, making it useful for sighting in at outdoor ranges. This model includes 12 LR41 batteries.
  • Red Laser Boresighter: Offers reliable performance at a lower price point. The red laser works well in most indoor settings and for shorter-range applications. This model includes 3 LR41 batteries and provides the functionality needed for basic boresighting tasks.

Both laser colors project a reference point from your barrel onto a target to establish alignment with your sighting system.

Sightmark Precision Boresighter Benefits

The Sightmark Precision Laser Boresighter offers enhanced features:

  • Brass construction for chamber fit
  • Laser module for brightness and distance capability
  • Includes AG5 batteries (2)
  • Durability for frequent use
  • Compatible with various calibers

This option delivers consistent results for users seeking reliability from their boresighting tool.

Quick Zeroing Process

Using a laser boresighter simplifies the sighting-in process:

       1. Make sure the firearm is not loaded and is always aimed in a safe direction.

       2. Insert the boresighter into the chamber or muzzle (depending on the model).

       3. Activate the laser to project a dot onto your target at your preferred zeroing distance.

       4. Adjust your sights or optic until aligned with the laser reference point.

       5. Remove the boresighter and confirm zero with live fire (adjusting as needed).

This procedure can reduce the ammunition needed for zeroing, saving time and money while achieving a starting point for final adjustments. For firearms with multiple optics like red dots paired with magnifiers, a boresighter helps ensure proper alignment between all components.

Caliber Compatibility and Design

Our laser boresighters work with multiple calibers:

  • Muzzle Design: Fits into the muzzle end of many common firearms
  • Caliber Range: Works with calibers from .22 to .50 for rifles and pistols
  • Fit System: Self-centering design helps ensure alignment

The Sightmark model offers additional options with its chamber-based design for specialized firearms or those outside standard caliber ranges.

Applications Beyond Initial Zeroing

While mainly used for establishing a baseline zero for new optics, laser boresighters can also help with:

  • Checking zero retention after transportation
  • Checking alignment between multiple optics on the same firearm
  • Training new shooters on sight alignment principles
  • Checking firearms that may have been bumped
  • Setting up multiple zero distances for the same optic

A laser boresighter is particularly valuable when setting up complex optics systems like Holosun magnifier combos, where proper alignment is critical for effective use.

Boresighter Accuracy and Limitations

Laser boresighters provide a starting point for zeroing but have some limitations:

  • They establish an approximation of zero that typically gets you on paper at 25-100 yards
  • Final adjustments with live ammunition are still necessary for precise zeroing
  • Accuracy can be affected by how the device centers in the barrel
  • They work best when used at the actual distance you intend to zero your firearm

Most users find that a laser boresighter gets them closer to final zero, reducing the ammunition and time needed to dial in their optics.

Optic Compatibility and Setup

Laser boresighters work with virtually all sighting systems, including:

  • Red dot sights (all footprints)
  • Magnified optics and scopes
  • Iron sights
  • Holographic sights
  • Prism scopes

For pistols with adapter plates or other mounting solutions, boresighters help verify proper alignment after installation, ensuring your optic is appropriately positioned  relative to your barrel. Shop today at Freedom Gorilla

Frequently Asked Question

Our boresighters work with most common firearms within standard caliber ranges, including rifles, shotguns, and handguns. Some specialized firearms may not be compatible with universal muzzle-style boresighters.

For good results, set your target at the distance you intend to zero your firearm. However, 25 yards works well for most applications and provides a good starting point.

While boresighters provide a starting point, final zero confirmation with live ammunition is still necessary due to factors like bullet trajectory and firearm characteristics that a boresighter cannot account for.

Green lasers tend to be easier to see in bright daylight and over greater distances, though they are typically more expensive. Red lasers work well in most standard conditions and provide better value. Choose based on your typical shooting environment and budget.

Battery life varies by model and use but typically provides 1-2 hours of operation. Since boresighting sessions are usually brief, most users regularly use them before needing replacement batteries. Our laser boresighters help make the zeroing process more efficient for firearms and optic combinations.
