Dewey 20 Caliber 5-40M Bore Brush 3/Pack Review

First Thoughts on the Dewey 20 Caliber 5-40M Bore Brush 3/Pack

As an outdoor and tactical gear specialist with over a decade under my belt, I’ve seen countless cleaning tools come and go. The Dewey 20 Caliber 5-40M Bore Brush 3/Pack piqued my interest because maintaining precision firearms, especially those chambered in smaller calibers like .20, demands specialized equipment. This brush pack promises a solution to a common problem: effective cleaning without the misleading copper fouling indicators.

My old brass brushes were constantly throwing me curveballs. Those false positives wasted time and solvent. I needed a reliable cleaning system that delivered honest results.

Upon receiving the Dewey brush pack, I immediately noticed the difference in construction compared to my standard brass brushes. The aluminum components felt solid and well-machined. The nylon bristles were densely packed and appeared ready to tackle stubborn fouling.

I’ve used brands like Hoppe’s and Bore Tech in the past, but the Dewey brushes stood out for their unique material choices, specifically the aluminum core and coupling. This design eliminates the possibility of false copper fouling readings, a significant advantage. My initial impression was positive; I was eager to see if these brushes would live up to their claims.

First Use Experience

I tested the Dewey 20 Caliber 5-40M Bore Brush 3/Pack after a long day at the range with my custom .20 caliber AR-15. The rifle had seen a few hundred rounds, and the bore was definitely fouled. I applied my usual bore solvent and began cleaning with one of the Dewey brushes.

The brush moved smoothly through the bore. The dense nylon bristles provided excellent scrubbing power. After just a few passes, I noticed a significant amount of carbon and powder residue being removed.

The biggest surprise was the complete absence of any blue-green staining on my cleaning patches. It was refreshing to see the actual color of the fouling without the interference of dissolved brass. I didn’t have to question whether or not the bore was actually clean.

Extended Use & Reliability

After several weeks of regular use, the Dewey 20 Caliber 5-40M Bore Brush 3/Pack continues to impress. The brushes have held up remarkably well. The nylon bristles show minimal wear, even after repeated use with aggressive solvents.

I have noticed no degradation of the aluminum core or coupling. The brushes clean easily with solvent and a quick wipe down. These brushes have significantly streamlined my cleaning process.

Compared to my old brass brushes, the Dewey brushes offer superior longevity and reliability. Their ability to eliminate false positives makes them an indispensable tool for any serious shooter who wants to achieve a truly clean bore.
