J. Dewey Sako Adjustable Bore Saver Review

Exploring the J. Dewey Sako Adjustable Bore Saver: My Review

In the meticulous world of firearm maintenance, protecting the integrity of a rifle’s bore is paramount. This is precisely where the J. Dewey Sako Adjustable Bore Saver enters the picture, offering a refined solution to a common problem. As an equipment specialist with over a decade of experience across diverse environments, I’ve encountered my fair share of tools designed to simplify and enhance maintenance. My journey to this particular bore saver began with the persistent annoyance of cleaning solvents finding their way into the rifle’s receiver during cleaning, an issue that can degrade accuracy and cause long-term damage. While many generic bore guides exist, I was specifically looking for something that offered a more robust and reliable seal, especially for my .17 caliber firearms where precision is critical. I briefly considered simpler, fixed-size models, but the adjustable nature of this unit promised broader compatibility and a more tailored fit. My initial impression upon unboxing was one of quiet satisfaction; the build quality felt solid and purposeful, a welcome departure from some of the flimsier alternatives I’d previously encountered.

Real-World Testing: Putting J. Dewey Sako Adjustable Bore Saver to the Test

My testing ground for the J. Dewey Sako Adjustable Bore Saver was my personal workshop and my dedicated range bench. I subjected it to repeated cleaning cycles on a variety of my .17 caliber bolt-action rifles, including those with slightly different chamber dimensions. The immediate environment involved typical workshop dust and the occasional spray of cleaning solvents, all of which are standard conditions for any serious firearm enthusiast. I focused on how effectively the bore saver kept liquids out of the receiver and how snugly it seated against the bolt face.

First Use Experience

My initial foray with this unit was straightforward, requiring minimal fuss to integrate into my existing cleaning routine. I slid it into the action, replacing the bolt as intended, and immediately noticed how it centered itself within the receiver. The anodized aluminum rod guide tube felt robust, providing a stable platform for my cleaning rod. My main concern was the seal; I ran a solvent-soaked patch through the bore, and was pleased to see that no liquid managed to seep past the O-rings to seal the chamber and keep solvents/oils out of the receiver. This was a significant improvement over previous experiences.

Extended Use & Reliability

After several weeks of consistent use, this bore saver has proven itself to be a durable and reliable component of my cleaning kit. It has endured probably two dozen cleaning sessions, and I haven’t noticed any degradation in its performance. The adjustable locking collar remains secure, and the O-rings show no signs of cracking or becoming brittle, even after being exposed to various cleaning agents. Compared to the cheaper plastic units I’ve used in the past, this J. Dewey product feels built to last, with no discernible wear on the aluminum guide tube or the sealing components. Cleaning it is as simple as wiping it down, and it stores easily in my cleaning case, taking up minimal space.

Breaking Down the Features of J. Dewey Sako Adjustable Bore Saver

Specifications

The J. Dewey Sako Adjustable Bore Saver is designed with precision and durability in mind. It features an anodized aluminum rod guide tube, which offers a smooth, low-friction surface for cleaning rods to pass through. This material choice significantly enhances its longevity and resistance to corrosion compared to plastic alternatives. The unit boasts an adjustable locking collar, a key feature that allows for a custom fit across different bolt actions. This adjustability ensures a snug seal, preventing unwanted contaminants from entering the rifle’s receiver.

The inclusion of O-rings to seal the chamber and keep solvents/oils out of the receiver is critical for its function. These O-rings create a barrier that protects the delicate internal mechanisms of the firearm during the cleaning process. The overall length is 10 in, making it suitable for a wide range of rifle actions. For those concerned about specific calibers, this model is particularly specified for .17 Caliber firearms, ensuring a precise fit and minimizing wobble. The quantity provided is one unit, making it a focused purchase for a specific need. The manufacturer, J. Dewey, is known for its commitment to producing quality gun cleaning accessories. The color is a practical Black/Silver finish.

Performance & Functionality

The core function of the J. Dewey Sako Adjustable Bore Saver is to protect the rifle’s action during cleaning, and it excels at this task. By replacing the bolt, it creates a perfectly centered guide for cleaning rods, preventing them from scraping against the chamber walls or the bolt raceways. The adjustable locking collar is a standout feature here; it allows me to fine-tune the fit, ensuring a tight seal that completely prevents solvents and oils from migrating into the receiver. This is particularly important for .17 caliber firearms, where even minor fouling can impact accuracy.

The smooth anodized aluminum rod guide tube ensures that cleaning patches and brushes move effortlessly, reducing the physical effort required and the risk of snagging. I found it to be significantly more effective than generic, non-adjustable bore guides, which can sometimes be too loose or too tight, leading to potential damage or ineffective sealing. While it’s designed for .17 caliber, the adjustability suggests it might accommodate slightly larger calibers with a very snug fit, though its primary optimization is for the smaller bores. The unit performs precisely as advertised, meeting and exceeding my expectations for its intended purpose.

Design & Ergonomics

The design of the J. Dewey Sako Adjustable Bore Saver is intentionally functional and robust. The use of anodized aluminum for the main body speaks to its intended durability; it feels solid and substantial in hand, a stark contrast to the lightweight, often brittle plastic of cheaper alternatives. The adjustable locking collar is intuitively designed, with a knurled surface that provides ample grip for tightening and loosening, even with slightly oily fingers. Its placement and operation are logical, allowing for quick adjustments without fumbling.

The inclusion of the O-rings is a testament to thoughtful engineering, addressing the common issue of solvent seepage. They are well-seated and appear to be made of a resilient material that should withstand repeated contact with cleaning chemicals. The overall length of 10 in is practical for most bolt-action rifle platforms, providing sufficient clearance for manipulation within the receiver. There’s a satisfying heft to the unit, suggesting it’s built to withstand the rigors of regular workshop use.

Durability & Maintenance

From my experience, the J. Dewey Sako Adjustable Bore Saver is built for longevity. The anodized aluminum rod guide tube is highly resistant to scratches and corrosion, meaning it should maintain its smooth operation for years to come. The adjustable locking collar mechanism also appears robust, with no signs of stripping or loosening after repeated adjustments. The O-rings are the most likely components to experience wear over time, but their quality construction suggests they will last a considerable period before needing replacement.

Maintenance is straightforward; a quick wipe-down with a solvent-dampened cloth after each use is all that’s needed to keep it clean and functional. It’s important to ensure the O-rings are free of debris to maintain a proper seal. Unlike some delicate tools, this bore saver doesn’t require any specialized care. It’s a tool designed to be used and cleaned, and it handles that process exceptionally well.

Accessories and Customization Options

The J. Dewey Sako Adjustable Bore Saver is a self-contained unit, and as such, it doesn’t come with external accessories or extensive customization options in the traditional sense. Its primary “customization” lies within its adjustable locking collar, which allows for a tailored fit to different bolt dimensions. This inherent adjustability makes it a versatile tool for .17 caliber rifles. The product is designed to work with standard cleaning rods and brushes, which are typically purchased separately by firearm owners.
