Brownells Standard Line Bronze Rifle Brush 375 Caliber 12 Pack

A Brownells Standard Line Bronze Rifle Brush in 375 caliber is a cleaning essential for shooters who maintain their own rifles. This 12-pack bulk option gives you extras for the range, the shop, and backup at home — because a quality bore brush is too useful to run out of. Each brush is purpose-built from phosphor bronze wire wound onto a one-piece steel shank, designed to scrub fouling and residue thoroughly without unnecessary wear on your bore.

Bronze bristles are the standard choice for rifle cleaning: they're tough enough to remove stubborn carbon and copper buildup, yet gentler on steel than steel-core brushes. The looped and wound construction (not twisted and cut) means a more consistent bristle pattern and longer service life per brush. For 375 caliber rifles, you get the thread size and bristle diameter matched to your bore — these brushes work with standard rifle cleaning rod systems.

Whether you're a hunter who cleans between seasons, a regular range shooter, or someone who keeps a well-stocked cleaning kit, a dozen brushes means you won't be caught short. Buy once and spend less per brush than purchasing them individually.

Frequently Asked Questions

What thread size does a 375 caliber Brownells bore brush use?

The 375 caliber brush in this pack uses 8-32 threads, the standard thread size for most rifle calibers except .17 and .20 caliber rifles, which use 5-40.

Will these brushes fit my standard rifle cleaning rod?

Yes — these brushes are designed to work with standard rifle cleaning rod systems. The 8-32 thread on the 375 caliber brush is the industry standard, so it will fit most commercial cleaning rods and handle kits.

Why choose bronze bristles for rifle cleaning?

Phosphor bronze is effective at removing carbon and copper fouling without the hardness of steel-core brushes, which can scratch and wear your bore over time. Bronze offers a good balance of cleaning power and bore safety across regular use.

Why buy a 12-pack instead of single brushes?

Bore brushes are consumable items — bristles eventually wear out with use. A 12-pack gives you spares for the range, backups in multiple cleaning kits, and a lower per-brush cost than buying individually.
