Let’s Dive into Bushnell Magnetic Boresighter Rifle Scope Accessory
The Bushnell Magnetic Boresighter Rifle Scope Accessory promises a quick and easy way to get your rifle scope roughly aligned before heading to the range. Bushnell aims to simplify the boresighting process by eliminating the need for traditional arbors. This accessory magnetically attaches to the muzzle.
As someone who’s spent countless hours helping friends and customers zero their rifles, I’m always on the lookout for tools that can save time and ammo. The promise of a universal, arbor-free boresighter immediately piqued my interest.
My initial impression was mixed. The compact size was appealing, but the magnet’s strength seemed questionable right out of the box. I’ve used traditional laser boresighters and spud-type optical boresighters before, both with their own drawbacks.
Traditional laser boresighters often require multiple arbors to fit various calibers. Spud-type optical boresighters, while more universal, can be bulky and sometimes difficult to align perfectly. The Bushnell Magnetic Boresighter Rifle Scope Accessory, with its promise of universal fit and magnetic attachment, aimed to address these issues. However, I was skeptical about whether the magnet alone could provide sufficient and consistent alignment.
My first impression was a mix of cautious optimism and a healthy dose of skepticism. The concept was intriguing, but the execution would determine whether this tool lived up to its claims.
Real-World Testing: Putting Bushnell Magnetic Boresighter Rifle Scope Accessory to the Test
First Use Experience
I first tested the Bushnell Magnetic Boresighter Rifle Scope Accessory at my local shooting range during a relatively calm day with clear skies. I used it on a .308 bolt-action rifle, a 5.56 AR-15, and a .22LR rifle, all equipped with different scopes.
The initial attachment was easy enough, but I immediately noticed the magnet wasn’t as strong as I’d hoped. On the .308, it held reasonably well, but on the lighter AR-15, even a slight bump caused it to shift. The most significant issue arose with the .22LR; the smaller barrel diameter provided very little surface area for the magnet to grip, rendering it almost unusable.
The etched glass reticle was clear and easy to see, but the lack of any leveling mechanism made accurate alignment challenging. After making adjustments based on the boresighter’s image, my first shots at 25 yards were on the paper but far from the bullseye. I had to make significantly more adjustments than usual to get properly zeroed.
Extended Use & Reliability
After several range sessions spanning a few months, the Bushnell Magnetic Boresighter Rifle Scope Accessory‘s limitations became more apparent. The magnet’s inconsistent grip continued to be an issue, especially when dealing with different barrel profiles and muzzle devices.
The aluminum body showed no significant signs of wear, but the etched reticle’s lack of adjustability remained a constant source of frustration. Cleaning was simple – a quick wipe with a cloth was usually sufficient. However, I never felt completely confident in its repeatability.
Compared to my experiences with traditional arbors, the Bushnell Magnetic Boresighter Rifle Scope Accessory consistently required more rounds to achieve a proper zero. While it did get me “on paper,” the savings in ammo were minimal, and the increased frustration offset any perceived convenience. Its performance was, frankly, disappointing.
Breaking Down the Features of Bushnell Magnetic Boresighter Rifle Scope Accessory
Specifications
The Bushnell Magnetic Boresighter Rifle Scope Accessory is designed for use on all calibers and firearms. It features a magnetic attachment system that eliminates the need for arbors. The unit incorporates an etched glass reticle for visual alignment.
- Material: Made primarily of metal (likely aluminum) for lightweight durability.
- Attachment: Utilizes a magnetic base to attach to the firearm’s muzzle.
- Reticle: Features an etched glass reticle for aiming reference.
- Compatibility: Supposedly compatible with all calibers and firearms.
- Dimensions: Compact size for easy storage and transport.
These specifications are critical because they dictate the boresighter’s usability and accuracy. The universal caliber compatibility is attractive, but the magnet’s strength and reticle’s adjustability (or lack thereof) significantly affect performance. A strong, reliable magnetic attachment is crucial for consistent alignment, and a leveling feature would greatly enhance accuracy.
Performance & Functionality
The primary function of the Bushnell Magnetic Boresighter Rifle Scope Accessory is to provide a rough initial alignment of a rifle scope with the firearm’s bore. In this regard, it partially succeeds. It will get you on paper at close ranges, saving you some initial rounds.
However, the inconsistent magnetic grip and lack of precise adjustment mechanisms significantly hinder its accuracy and repeatability. The claim of “easy sight in” is misleading, as it often requires significantly more fine-tuning at the range than with traditional methods. The tool’s weaknesses overshadow its strengths.
Design & Ergonomics
The Bushnell Magnetic Boresighter Rifle Scope Accessory boasts a compact and lightweight design, making it easy to store and transport in a range bag. Its simplicity is appealing, but the lack of features like a leveling bubble or adjustable reticle detracts from its overall usability.
There’s virtually no learning curve. Simply attach it to the muzzle and look through the scope. However, the lack of precision in the design makes achieving a truly accurate initial alignment challenging.
Durability & Maintenance
The metal construction of the Bushnell Magnetic Boresighter Rifle Scope Accessory suggests reasonable durability for occasional use. The lack of moving parts minimizes the risk of mechanical failure.
Maintenance is straightforward. Simply wipe down the surface with a clean cloth to remove any residue. However, the etched reticle is not user-replaceable, so any damage to it would render the entire unit unusable.
Accessories and Customization Options
The Bushnell Magnetic Boresighter Rifle Scope Accessory does not come with any additional accessories. There are no customization options available for this product. Its simplicity is both a blessing and a curse. While it reduces complexity, it also limits its versatility and adaptability to different firearms and shooting scenarios.

Pros and Cons of Bushnell Magnetic Boresighter Rifle Scope Accessory
Pros
- Simple to use and requires no arbors.
- Compact and lightweight for easy storage.
- Etched glass reticle is clear and easy to see.
- Potentially saves some initial rounds getting “on paper.”
- Universal caliber compatibility (in theory).

Who Should Buy Bushnell Magnetic Boresighter Rifle Scope Accessory?
The Bushnell Magnetic Boresighter Rifle Scope Accessory might be suitable for casual shooters who own a wide variety of firearms and need a very rough initial alignment tool. It could also be useful for individuals with limited experience who are intimidated by traditional boresighting methods.
However, serious hunters, competitive shooters, or anyone seeking precise and repeatable results should skip this product. It simply lacks the accuracy and reliability required for critical applications.
Must-have accessories for use with this product would include a separate leveling kit for your scope and possibly some tape to secure the boresighter to the muzzle for a better hold.
Conclusion on Bushnell Magnetic Boresighter Rifle Scope Accessory
The Bushnell Magnetic Boresighter Rifle Scope Accessory promises a quick and easy solution for boresighting, but its execution falls short of its ambition. While the concept of a universal, arbor-free boresighter is appealing, the weak magnet and lack of precise adjustment mechanisms significantly limit its accuracy and reliability.
At a price of $40.89, the value proposition is questionable. For a similar price, you could purchase a decent set of traditional arbors or invest in a more accurate laser boresighter.
I would not personally recommend the Bushnell Magnetic Boresighter Rifle Scope Accessory to anyone seeking a reliable and accurate boresighting tool. Its inconsistent performance and lack of precision make it more of a frustration than a convenience. Save your money and invest in a better solution for getting your rifles properly zeroed.
