Brownells Standard Line Brush, Nylon, .338 Caliber Rifle, 12 Pack

A Brownells Standard Line Brush in nylon for .338 caliber rifles gives you a dozen quality bore brushes built to handle modern aggressive copper solvents without compromising your rifle's accuracy. Whether you're running a heavy magnum or a precision long-range .338, these brushes are engineered to scrub fouling effectively while the nylon bristles resist the wear that comes from today's potent bore cleaners. Buy in bulk, save money, and always have a fresh brush on hand—no more rationing or making do with a worn-out one mid-cleaning session.

Brownells invested in one-piece, looped and wound steel shanks rather than cheaper two-piece twisted designs that fail mid-stroke. That construction matters: a shank that stays true keeps your brushing action consistent and your bore safe from accidental scratching. Nylon bristles won't cause the kind of damage that costs you accuracy or rifle resale value, and they're tough enough to stand up to the strongest copper and bronze-dissolving solvents on the market.

The 12-pack format is built for shooters and gunsmiths who clean regularly. Stock your range bag, your cleaning kit at home, and your truck; rotate them so bristles dry fully between uses and last longer. At 3.27 inches overall with standard 8-32 threads, these fit the rod you already own and work seamlessly with your favorite cleaning system.

Frequently Asked Questions

Will these nylon brushes work with strong copper solvents?

Yes. Nylon bristles are specifically engineered to resist the wear and degradation caused by aggressive modern bore cleaners that attack copper and bronze fouling. They'll hold up where softer bristles fail.

What threads do these brushes use?

These .338 caliber brushes have 8-32 threads, which is the standard thread size for rifle bore brushes and will fit any cleaning rod with standard 8-32 compatibility.

Why buy a 12-pack instead of individual brushes?

A 12-pack gives you better value per brush and lets you rotate brushes between cleanings so bristles dry completely, extending their lifespan. It's the economical choice for active shooters and anyone who cleans multiple rifles regularly.

Will these scratch my barrel?

No. Nylon bristles are designed not to cause accuracy-ruining scratches. The one-piece steel shank construction also ensures consistent, safe contact with your bore during cleaning.
