Breakthrough Clean BT357 38/9mm Nylon Bristle Bore Brush - Premium Gun Cleaning Tool

The Breakthrough Clean BT357 38/9mm nylon bristle bore brush is a straightforward, effective tool for pistol cleaning. If you shoot .38 Special, 9mm, or similar mid-caliber handguns and want reliable bore maintenance without overthinking it, this brush handles the job. Nylon bristles are gentle enough not to damage barrel steel, yet stiff enough to scrub out powder residue and fouling. It threads onto standard cleaning rods, so it integrates seamlessly into any existing gun cleaning kit.

Breakthrough Clean Technologies focuses on practical, no-nonsense gun care products. This brush does exactly what it's supposed to do—get into the bore, agitate debris, and come out clean. Whether you're running a range day cleanup or regular maintenance between hunting trips, a dedicated bore brush tailored to your caliber beats a one-size-fits-all alternative.

Keep one in your range bag or cleaning kit. Bore brushes wear over time and use, so having a spare on hand means you're never caught without one when you need to get downrange again.
