Brownells Standard Line Brush, 20 Gauge Shotgun, Ss, 12 Pack

The Brownells Standard Line Brush for 20 gauge shotguns comes in a practical 12-pack bulk bundle—ideal for shooters who maintain multiple shotguns, run a shop, or simply don't want to hunt for a brush when it's time to clean. These stainless steel bore brushes are built tough for serious fouling and carbon removal, making them a go-to choice for hunters and clay shooters who demand reliability between range sessions and in the field.

Stainless steel bristles deliver aggressive cleaning action that cuts through leaded bores, heavy carbon fouling, and rust buildup that softer brass brushes struggle with. The key to Brownells' durability is the one-piece, looped and wound shank—not the flimsy twisted-and-chopped design found on cheaper alternatives. That construction means these brushes hold up to repeated use and won't shed bristles or fail mid-cleaning. Just keep in mind that the hard-charging action of stainless steel, while effective, can accelerate bore wear with extended use; they're best reserved for problem-solving rather than routine maintenance on a prized barrel.

At 2-7/8" overall length with standard 5/16"-27 male threads, these brushes fit most cleaning rod systems and bore guide setups. The 12-pack format makes sense for serious shooters: keep a few on the bench, stash spares in your range bag and gun safe, and you'll always have a fresh brush ready. Stock a set and stop worrying about running out.

Frequently Asked Questions

Will these brushes fit my cleaning rod?

Yes, as long as your rod uses standard 5/16"-27 male threads. This is the most common thread size for shotgun cleaning systems. Check your rod's thread size before ordering to confirm compatibility.

When should I use stainless steel brushes versus brass?

Stainless steel brushes like these are aggressive cleaners, ideal for removing heavy carbon, lead buildup, and rust from neglected or heavily shot bores. Brass brushes are gentler and better for routine maintenance. Use stainless steel when you need serious cleaning power, but avoid regular use on barrels you want to preserve, as the harder bristles can accelerate wear.

Why buy a 12-pack instead of individual brushes?

The bulk pack is more economical per brush and practical if you own multiple shotguns, shoot frequently, or run a shop. You'll always have a fresh brush on hand and won't run out during a cleaning session. It's also a smart way to stock up for long-term use.
