Was the Bushnell Magnetic Boresighter Rifle Scope Accessory the Right Choice?
The Bushnell Magnetic Boresighter Rifle Scope Accessory promises a quick and easy way to get your rifle scope zeroed. Bushnell claims its magnetic attachment eliminates the need for traditional arbors, making it compatible with all calibers and firearms. The etched glass reticle is another selling point, aimed at providing a clear and precise reference.
As someone who has spent years helping customers sight in their rifles, I was intrigued. I needed a faster, more universal boresighting solution for my personal range and for quick checks on customers’ firearms at my shop. The Bushnell Magnetic Boresighter Rifle Scope Accessory seemed like it could potentially streamline the process and save a lot of time and ammunition.
Upon unboxing, I was immediately struck by its compact size and simple design. It felt solid, constructed primarily of metal, which gave me a decent first impression of its durability. Comparing it to the traditional arbors I’m used to, the magnetic concept was definitely appealing from a convenience perspective. I had considered a laser boresighter, but the Bushnell‘s reliance on an optical system seemed like it would provide a more reliable point of reference, less susceptible to battery issues or electronic malfunctions.
My initial excitement was tempered with a little skepticism. The strength of the magnet was my primary concern, especially after reading some customer reviews mentioning it being weak. I was eager to see if it could hold securely onto various muzzle types without slipping or spinning, and whether the reticle would maintain its alignment under recoil.
Real-World Testing: Putting Bushnell Magnetic Boresighter Rifle Scope Accessory to the Test
First Use Experience
My first test was at my local shooting range, using a variety of rifles: a .223 AR-15, a .308 bolt-action, and even a 12-gauge shotgun. I set up targets at 25 yards, anticipating the promised “on paper” result. The initial attachment proved to be somewhat problematic.
The magnet on the Bushnell Magnetic Boresighter Rifle Scope Accessory didn’t grip the AR-15’s muzzle brake as securely as I’d hoped. It required careful balancing and a very steady hand to prevent it from shifting. The .308 presented a slightly better surface, but still required constant monitoring. The shotgun was a no-go; the flared muzzle simply provided no adequate surface for the magnet to adhere to.
Extended Use & Reliability
After a few weeks of intermittent use, my initial reservations were unfortunately confirmed. The Bushnell Magnetic Boresighter Rifle Scope Accessory‘s inconsistent magnetic grip became a major source of frustration. On some rifles with perfectly flat muzzles, it worked reasonably well, getting me close to center at 25 yards.
However, on any firearm with even a slight taper or obstruction near the muzzle, the magnet simply wasn’t strong enough to maintain a stable position. The slightest bump would cause it to rotate, rendering the reticle useless. I tried cleaning the magnet and the muzzle surfaces meticulously, but the problem persisted. I even attempted to use tape to secure it, which defeats the purpose of a “quick” sighting-in tool.
Maintenance was straightforward, as there are no moving parts or electronics to worry about. However, the unreliable magnetic attachment and the lack of repeatable results made it a less-than-ideal addition to my toolkit. Ultimately, the Bushnell Magnetic Boresighter Rifle Scope Accessory didn’t outperform my traditional arbors, and in many cases, it proved to be significantly less reliable.

Performance & Functionality
The Bushnell Magnetic Boresighter Rifle Scope Accessory aims to quickly get shooters “on paper” at close range. In ideal conditions (flat, unobstructed muzzle), it can achieve this goal, providing a rough zero. The etched reticle is clear and easy to see, aiding in the alignment process.
However, its performance is heavily dependent on the firearm’s muzzle design. The weak magnet consistently struggles to hold securely on anything but the most perfectly flat surfaces. This inconsistency is a major drawback, making it unreliable and ultimately frustrating to use. It simply doesn’t meet expectations for a truly universal boresighting tool.
Design & Ergonomics
The Bushnell Magnetic Boresighter Rifle Scope Accessory features a simple, cylindrical design. Its compact size makes it easy to store and transport. However, the lack of any leveling features or adjustable components is a significant oversight.
The absence of a built-in level makes it difficult to ensure the boresighter is perfectly vertical, which can introduce errors in the alignment process. The reliance on the magnetic attachment as the sole means of securing the device also contributes to its ergonomic shortcomings.
Durability & Maintenance
Constructed from metal, the Bushnell Magnetic Boresighter Rifle Scope Accessory feels reasonably durable. There are no delicate parts to break or wear out under normal use. Maintenance is minimal, requiring only occasional cleaning to remove debris from the magnet and reticle.
However, the long-term durability is somewhat questionable, given the potential for the magnet to weaken over time. Even with careful handling, the inconsistent grip and lack of secure attachment points suggest that the Bushnell Magnetic Boresighter Rifle Scope Accessory might not withstand heavy or frequent use.
Accessories and Customization Options
The Bushnell Magnetic Boresighter Rifle Scope Accessory comes with no additional accessories. There are no customization options available. Its simplicity is both a strength and a weakness.
While it eliminates the need for specific arbors, it also limits its adaptability to different firearm types and sighting systems. The lack of compatibility with external leveling devices or alignment tools further restricts its versatility.
Pros and Cons of Bushnell Magnetic Boresighter Rifle Scope Accessory
Pros
- Easy to use on firearms with perfectly flat, unobstructed muzzles.
- Compact and lightweight design.
- Durable metal construction.
- Etched glass reticle provides a clear aiming point.
- Potentially faster than using traditional arbors on compatible firearms.
Cons
- Weak magnet provides an inconsistent grip on most firearms.
- Lacks leveling features, making it difficult to ensure accurate alignment.
- Not truly universal – struggles with tapered or obstructed muzzles.
- Does not provide repeatable settings, rendering it useless for anything other than a rough, initial alignment.
Who Should Buy Bushnell Magnetic Boresighter Rifle Scope Accessory?
The Bushnell Magnetic Boresighter Rifle Scope Accessory might be suitable for shooters who primarily use firearms with perfectly flat, unobstructed muzzles and need a very basic, initial sight alignment. It could be beneficial for those seeking an extremely compact and lightweight boresighting solution.
However, anyone who owns a variety of firearms with different muzzle designs or requires a precise and repeatable boresighting method should skip this product. This includes serious hunters, competitive shooters, and gunsmiths. A traditional boresighting kit with arbors or a high-quality laser boresighter would be a much better investment.
Conclusion on Bushnell Magnetic Boresighter Rifle Scope Accessory
The Bushnell Magnetic Boresighter Rifle Scope Accessory promises a convenient and universal solution for sighting in rifles. However, its inconsistent magnetic grip and lack of leveling features significantly limit its effectiveness. The asking price of $40.89 seems high for a product that fails to deliver on its core promises.
I cannot personally recommend the Bushnell Magnetic Boresighter Rifle Scope Accessory. Its unreliability and limited compatibility make it a frustrating and ultimately ineffective tool. Invest in a more robust and versatile boresighting solution that provides consistent and accurate results. Your time and ammunition will thank you.
