Brownells Special Line Brass Rifle Brush 17 Caliber 5-40 Tpi 12 Pack

Proper rifle maintenance starts with the right cleaning tools, and a Brownells Special Line Brass Rifle Brush 17 Caliber is built to protect your barrel while delivering thorough cleaning. This 12-pack of precision brushes pairs a one-piece brass shank with phosphor bronze bristles—the kind of construction that separates field-proven gear from disposable alternatives. Whether you're maintaining a prized varmint rifle or keeping a workhorse .17 running reliably, these brushes eliminate the risk of shank scratches that can compromise your bore.

The key to Brownells' Special Line design is its attention to detail. The brass shank is looped and wound as a single piece rather than twisted together and cut off—a process that creates a stronger, more uniform tool. That solid construction matters when you're running brushes repeatedly through a precision bore. Pair that with a brass coupling (also non-scratch) and you get a brush that can handle regular cleaning without introducing the slightest marring to your rifle's most critical component.

The phosphor bronze bristles are scrubbing wire rated for longevity and aggressive fouling removal. They'll cut through carbon, copper, and powder residue without degrading quickly, so a 12-pack gives you brushes for deep cleaning sessions, quick field maintenance, or simply having backups on hand. The 5-40 TPI thread fits 17 caliber rods and is compatible with most standard cleaning rod systems, making this a straightforward drop-in for your existing kit.

Frequently Asked Questions

What thread size do 17 caliber Brownells brushes use?

17 caliber brushes in the Special Line come with 5-40 TPI male threads, which mate with standard 17 caliber cleaning rods. Confirm your rod's thread before ordering.

Why use brass shanks instead of steel for rifle brushes?

Brass is softer than steel and won't scratch or mar the inside of your bore if the shank contacts the walls during cleaning. This is especially important for high-precision rifles where even minor scratches can affect accuracy or resale value. Brownells' one-piece looped and wound construction also eliminates weak points that could snag or fail.

How many brushes come in a pack?

Each box contains 12 brushes, giving you plenty for routine cleaning, deep maintenance sessions, or sharing among multiple rifles.

Can I use these brushes with my 17 HMR or other 17 caliber rifle?

Yes, as long as your cleaning rod uses 5-40 TPI threading. Check your rod's specifications to confirm compatibility before use.
