Carbon buildup, plastic wad fouling, lead deposits - a 12-gauge shotgun barrel collects all of it. This 12 GA brass bore brush is built to scrub it out. Phosphor bronze bristles are tough on residue but softer than barrel steel, so the brush wears down over time - your bore doesn't.

The 12 gauge is the most popular shotgun gauge in America. Its larger bore (0.729") means more powder residue and heavier wad contact than smaller gauges. If you shoot slugs or buckshot, lead builds up in the forcing cone area. This shotgun cleaning brush paired with a quality bore solvent takes care of it.

Run it through after each range session, replace when the bristles no longer fit snugly. A quick bore cleaning routine is the simplest gun cleaning habit that keeps your shotgun shooting straight.

Is 12 gauge the same as 12 bore?
Yes. "12 gauge" and "12 bore" mean the same thing - a barrel with an internal diameter of 0.729 inches. The term "bore" is more common in British English, while American shooters typically say "gauge." Either way, a 12 GA bore brush fits both.
What type of fouling does a 12 gauge shotgun barrel get?
Shotgun barrels deal with three main types of fouling: plastic wad residue from modern shells, lead deposits from slugs and buckshot, and carbon buildup from powder combustion. Plastic wad fouling is the most common and requires a stiff bore brush paired with a wad-dissolving solvent to remove effectively.
Can a brass bore brush damage my shotgun barrel?
No. Phosphor bronze bristles are significantly softer than the steel in your barrel - they physically cannot scratch or wear the bore. The brush wears down over time; your barrel does not. This has been confirmed by barrel manufacturers and gunsmiths for decades.
Should I use a brass or nylon bore brush for my 12 gauge?
Bronze is your primary cleaning brush - the stiffer bristles cut through carbon, lead, and plastic wad fouling that nylon cannot reach. Use a nylon brush for light maintenance between deep cleanings or when applying copper-dissolving solvents, since those solvents can react with bronze bristles and give false color readings.
Do I need both a bore brush and a bore mop for my shotgun?
They do different jobs. The bore brush scrubs fouling loose from the barrel walls. The bore mop absorbs solvent and lifts loosened residue out of the bore. Run the brush first with solvent, then follow with a mop or patches until they come out clean. Skipping the brush means the mop just pushes fouling around without breaking it free.
