Brownells Standard Line Bronze Rifle Brush 17 Caliber 12 Pack

A dozen bronze rifle brushes in 17 caliber—the kind of no-nonsense cleaning tool that separates a casual shooter from someone who actually maintains their gear. Brownells Standard Line Bronze Rifle Brushes come packed 12 to a box because serious cleaners burn through them, and buying in bulk means you're not rationing a tool that only costs pennies per use. Whether you're breaking in a new .17 or running a well-oiled cleaning rotation across your safe, having a dozen on hand means you'll never be caught short or tempted to skip a thorough bore cleaning.

These aren't generic brushes stamped from the same die as every other retailer's house brand. Brownells manufactures these with phosphor bronze bristles—the right material for aggressive scrubbing without damaging bore steel. The shank is one-piece, looped and wound construction rather than twisted wire chopped and crimped; that's a small detail that translates to a brush that won't shed bristles halfway through a cleaning session or fail when you need it most. At 3.26 inches overall length, they fit standard rifle cleaning rod configurations and thread directly onto 5-40 adapters (the correct sizing for .17 caliber).

If you're serious about rifle maintenance—whether you're a handloader, a precision shooter, or someone who simply refuses to let ammunition and negligence cost you accuracy—a bulk pack of quality bore brushes is one of those purchases that pays for itself in peace of mind. Brownells reputation in gunsmithing and reloading isn't built on hype; it's built on products that work the way they're supposed to, every time.

Frequently Asked Questions

What thread size do these brushes use?

The .17 caliber brushes in this pack use 5-40 thread pitch, which is the standard adapter size for .17 rifles. Make sure your cleaning rod jag or handle is equipped with a compatible 5-40 adapter.

Why buy a 12-pack instead of individual brushes?

Brownells bulk packs exist because shooters and gunsmiths go through brushes regularly. Having a dozen on hand means you can rotate them through cleaning cycles, replace worn ones without interrupting your maintenance schedule, and stock your cleaning kit or shop bench without repeated small orders.

Are these brushes safe to use on my rifle barrel?

Yes. Phosphor bronze is the industry standard for bore brushes precisely because it's hard enough to scrub fouling effectively but soft enough not to damage steel barrel steel. Unlike brass or steel brushes, bronze won't leave marks or wear the bore.

What's the difference between the one-piece wound shank and twisted-wire designs?

The one-piece looped and wound construction is more durable and won't unravel or shed wires during use. Twisted-wire brushes can separate under pressure or repeated cleaning, leaving bristles behind in the bore or failing mid-session. This design simply holds together better and lasts longer.
