Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) Review

The Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) Made a Bold First Impression

After a decade spent maintaining everything from vintage lever-actions to cutting-edge AR platforms, I’ve learned one thing: a clean bore is the key to accuracy and longevity. I’ve wrestled with countless bore brushes over the years, from the cheap, flimsy ones that shed bristles faster than a molting bird, to the overly aggressive brass brushes that can damage a firearm’s delicate rifling. My quest was simple: find a bore brush that strikes the perfect balance between cleaning power and barrel preservation, specifically for my .40 caliber firearms. The Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) promised to be that solution.

That promise is what led me to the Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm). I had been struggling with stubborn fouling in a Glock 22 I use for competitions. After reading about the brushes, I immediately ordered one online.

Upon unboxing, the Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) immediately impressed with its solid construction. The tightly packed nylon bristles felt stiff and ready for action, and the robust brass core exuded quality. This was definitely a step up from some of the cheaper brushes I’ve used that have flimsy wire cores.

Compared to the generic nylon brushes I usually grab at the local sporting goods store, the Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) felt significantly more substantial. I also considered a bronze brush, but worried about being too aggressive on my barrels. I chose the Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) for its promise of effective cleaning without excessive abrasion. My initial reaction was excitement; this looked like a tool that could actually make a difference in my cleaning routine.

Real-World Testing: Putting Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) to the Test

First Use Experience

My first test of the Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) came after a particularly grueling day at the range. I had put about 300 rounds through my Smith & Wesson M&P .40, leaving a considerable amount of powder residue and copper fouling in the barrel. Using the Breakthrough Clean solvent, I went to work.

The brush moved smoothly through the bore, providing noticeable resistance as the nylon bristles scrubbed away at the grime. It performed well, and the cleaning process was relatively quick. The brush conformed to the bore’s contours and didn’t bind up like some of the lesser quality brushes I’ve used in the past.

Afterward, inspecting the bore revealed a significant improvement. Most of the powder fouling was gone, and even some of the more stubborn copper deposits had been loosened. No issues arose during my first use, and I was impressed with how effectively it worked.

Extended Use & Reliability

After several weeks of consistent use, the Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) continues to impress. I’ve cleaned a variety of .40 caliber firearms with it, including pistols and carbines, and it has consistently delivered excellent results. The brush head hasn’t loosened or degraded, and the bristles remain stiff and effective.

After a month of cleaning approximately 10 barrels, the Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) shows minimal signs of wear. I make sure to clean the brush itself after each use, removing any accumulated fouling. Compared to other nylon brushes I’ve used, this one is significantly more durable, with no signs of bent or missing bristles.

Compared to my previous cleaning methods, using the Breakthrough Clean Nylon Bristle Bore Brush (.40 Cal / 10mm) has significantly improved the speed and effectiveness of my cleaning routine. I can confidently say it outperforms any other nylon brush I’ve used in this caliber.
