Brownells Heavy Weight Brush, Nylon, .410 Bore Shotgun, 12 Pack

Proper shotgun maintenance starts with the right bore brush, and the Brownells Heavy Weight Brush in .410 bore is built for serious cleaning work. This 12-pack of nylon brushes cuts through carbon, copper, and powder residue faster than standard brushes—the extra-stiff bristles bite hard on fouling without compromising the integrity of your shotgun's smoothbore. Whether you're breaking in a new gun, deep-cleaning after a heavy shooting session, or maintaining a well-used field piece, having a full dozen brushes on hand means you can rotate fresh ones through the bore without downtime.

Each brush features a one-piece brass shank that's looped and wound for strength and durability. That brass construction is key: it won't scratch your bore the way steel can, and it won't degrade under repeated exposure to solvents. The looped design also means you get consistent contact and controlled scrubbing action—no binding, no unnecessary force required.

The .410 bore specification matters. This isn't a generic brush; it's sized and weighted for the smaller diameter of .410 shotgun bores, so you get proper bristle engagement and effective cleaning. The standard 5/16"-27 male thread fits all Brownells brush handles and standard shotgun cleaning rod systems. At 2 7/8 inches overall length, these brushes are proportioned for efficient work in the bore and easy removal.

If you shoot .410s regularly—whether for small game, clay targets, or just enjoying a light-recoil shotgun—a bulk pack like this keeps you stocked and ready. Nylon bristles won't rust or degrade, so brushes from this pack will last through years of shooting seasons if stored properly.

Frequently Asked Questions

Will this brush fit my .410 shotgun cleaning rod?

Yes. The 5/16"-27 male thread is the standard specification for Brownells brush handles and most shotgun cleaning rods. If you're using an aftermarket system, confirm it accepts that thread size.

Are these brushes safe to use with all solvents?

Nylon bristles are solvent-resistant and won't deteriorate with standard shotgun cleaning solvents. That said, always follow your solvent's instructions and avoid submerging brushes for extended periods unnecessarily.

What's the advantage of a 12-pack over buying individual brushes?

A full dozen lets you keep fresh brushes rotating through regular cleaning sessions, maintain one set for storage, and have spares on hand. Over time, bristles can fray or wear, so having backups means you're never stuck without a usable brush.

Can I use these brushes with other gauges?

No. These are sized for .410 bore specifically. Using them in larger or smaller bores won't give you effective cleaning contact. Always match the brush gauge to your shotgun.
