Brownells Heavy Weight Brush, Nylon, 12 Gauge Shotgun, 12 Pack

Keeping a shotgun's bore clean isn't just about maintenance—it's about reliability when you need it. The Brownells Heavy Weight Brush for 12 Gauge shotguns is purpose-built to tackle the stubborn carbon and powder residue that standard soft brushes leave behind. This 12-pack gives you plenty of brushes on hand for regular cleaning cycles, whether you're running clay sports, hunting, or working through ammunition at the range.

What makes these brushes aggressive without being destructive is the heavy-weight nylon bristle construction. The extra-stiff bristles are large enough in diameter to scrub effectively inside a 12-gauge bore, yet they're safe to use on both rifled and smoothbore shotgun surfaces. You won't damage your gun's internals, and the nylon material won't break down when exposed to your preferred solvents—so you can keep using your proven cleaning routine without worry.

The brass shank is looped and wound in one piece, a design choice that matters: it resists scratching the bore and breech as you run the brush in and out. The standard 5/16"-27 male thread fits Brownells rod systems and most common cleaning rod setups, making this brush compatible with your existing gear. At 2 7/8" overall length, it's compact enough to work in confined spaces while giving you enough bristle reach to get the job done.

Frequently Asked Questions

Will this brush fit my cleaning rod?

Yes, if your cleaning rod uses a standard 5/16"-27 male thread. This is the most common size for shotgun and rifle cleaning rod systems. If you're unsure about your rod's thread size, check the documentation or test-fit one brush before committing the pack.

Can I use these brushes with any solvent?

The heavy-weight nylon bristles are solvent-resistant and won't deteriorate when exposed to standard gun cleaning solvents. You can safely use your preferred solvent without concern.

Is the nylon bristle safe on my shotgun's bore?

Yes. The bristles are stiff and aggressive enough to scrub stubborn deposits, yet they're soft enough to be safe on both smoothbore and rifled shotgun surfaces. The brass shank design also prevents scratching, so you're protected on both fronts.

Why buy a 12-pack instead of individual brushes?

A full set means you always have a fresh brush on hand for regular cleaning cycles, and you can leave brushes with different rods set up at your cleaning station or range bag without swapping them around.
