Bushnell Universal Magnetic Boresighter Review

First Thoughts on the Bushnell Universal Magnetic Boresighter

The Bushnell Universal Magnetic Boresighter promises a quick and easy way to get your firearms roughly zeroed, saving time and ammunition at the range. As someone with over a decade of experience in the outdoor and tactical gear world, I’m always skeptical of gadgets that claim to simplify complex processes, but the Bushnell name carries weight. I was looking for a more efficient way to initially sight-in rifles, especially after installing new optics, instead of wasting precious ammo trying to get on paper.

The compact packaging and promise of universal compatibility immediately appealed to me. The Bushnell Universal Magnetic Boresighter aims to streamline the sighting process, a task that can be tedious and expensive without the right tools. I’ve used laser boresighters in the past, but they often require specific arbors for each caliber, adding to the cost and complexity.

Unboxing the Bushnell Universal Magnetic Boresighter revealed a simple, straightforward design. The unit itself is surprisingly lightweight, primarily constructed of what appears to be durable polymer and a strong magnet. It feels well-assembled, if not overly robust. My initial impression was cautiously optimistic: it seemed easy enough to use, but the proof would be in the pudding – its accuracy and reliability in the field.

Compared to a traditional laser boresighter kit, which can cost upwards of $100 or more, the Bushnell Universal Magnetic Boresighter‘s price point of $34.99 is significantly more attractive. I chose this over a more expensive, caliber-specific laser boresighter because of its purported versatility and affordability. I was excited to see if it could deliver on its promises and become a valuable addition to my range bag.

Real-World Testing: Putting Bushnell Universal Magnetic Boresighter to the Test

First Use Experience

My first experience with the Bushnell Universal Magnetic Boresighter was at my local outdoor shooting range. I was sighting in a new scope on my AR-15 chambered in 5.56 NATO. I attached the Bushnell Universal Magnetic Boresighter to the muzzle of the rifle, ensuring a firm magnetic connection. The process was quick and required no tools.

I tested it in relatively dry conditions, with a slight breeze. The unit seemed stable and the projected grid was clearly visible on my target at 25 yards. Adjusting the scope to align with the grid was relatively straightforward, though I found it beneficial to use a stable rest for both the rifle and myself. After making the initial adjustments based on the Bushnell Universal Magnetic Boresighter, my first shot at 50 yards was surprisingly close to the bullseye. It saved me a significant amount of time and ammunition compared to starting from scratch.

Extended Use & Reliability

After several weeks of use on various firearms, the Bushnell Universal Magnetic Boresighter continues to hold up well. There are no noticeable signs of wear and tear on the polymer body. The magnet remains strong, providing a secure attachment to the muzzle.

Maintenance is minimal: simply wiping down the unit with a clean cloth after each use is sufficient. This simplicity is a major advantage. Compared to my previous experiences with more complicated laser boresighters, the Bushnell Universal Magnetic Boresighter is much easier and faster to use. It gets me “on paper” reliably and quickly, which is its primary function.

Breaking Down the Features of Bushnell Universal Magnetic Boresighter

Specifications

• Universal Compatibility: The Bushnell Universal Magnetic Boresighter is designed to work with virtually any caliber of firearm, from rifles to shotguns to handguns. Its magnetic attachment system adapts to different barrel diameters.
• Magnetic Attachment: The strong magnet securely attaches the boresighter to the muzzle of the firearm. This ensures stability during the sighting-in process.
• Grid Projection: The boresighter projects a grid pattern onto the target, allowing for easy alignment of the firearm’s sights or optic. It simplifies the process of making initial adjustments.
• Lightweight Design: The lightweight polymer construction of the Bushnell Universal Magnetic Boresighter makes it easy to transport and handle. It adds minimal weight to the firearm during use.
• Durable Construction: Despite its lightweight design, the Bushnell Universal Magnetic Boresighter is constructed from durable materials designed to withstand regular use. This is valuable for a tool destined for the range.

Performance & Functionality

The Bushnell Universal Magnetic Boresighter performs its core function – getting you close to zero – admirably. It’s not a substitute for live fire zeroing, but it significantly reduces the number of rounds needed to achieve a precise zero. The strong magnet ensures a stable platform, which is crucial for accurate boresighting.

The primary weakness is its inherent limitation: it’s an approximation, not a precise measurement. Small variations in barrel manufacturing or magnetic alignment can introduce slight errors. It meets expectations as a quick and easy tool for initial sight-in, but it’s essential to fine-tune with live fire.

Design & Ergonomics

The Bushnell Universal Magnetic Boresighter boasts a simple, functional design. The polymer construction keeps the weight down. The ergonomics are straightforward: it’s easy to attach and remove from the muzzle.

There is virtually no learning curve; anyone familiar with firearms can use it effectively within minutes. The lightweight design ensures it doesn’t interfere with the firearm’s balance.

Durability & Maintenance

The durable polymer construction suggests a reasonable lifespan with proper care. The simplicity of the design minimizes potential failure points.

Maintenance is straightforward, requiring only occasional cleaning with a dry cloth. There are no user-serviceable parts, so repair is not an option, but the low price point makes replacement a viable solution.

Accessories and Customization Options

The Bushnell Universal Magnetic Boresighter doesn’t come with any additional accessories. Its primary function is as a standalone boresighting tool. There are no customization options available.

It’s universally compatible in the sense that it works with a wide range of calibers. However, it doesn’t integrate with other aftermarket accessories in a meaningful way.
