Birchwood Casey Bc-41523 B/C Nylon Bore Brush 16Ga Red
The Birchwood Casey nylon bore brush in 16-gauge is a straightforward cleaning tool for shotgun owners who want reliable, repeatable maintenance without fuss. Red nylon bristles do the heavy lifting in the bore itself, scrubbing away powder residue, lead, copper, plastic wads, and carbon buildup with a multi-directional action that works into every corner. Unlike brass brushes, nylon returns to its original shape after each cleaning session, so you get consistent performance over many rounds without the brush becoming permanently splayed or less effective.
This isn't a specialty tool—it's the workhorse you grab for regular shotgun cleaning after clay shoots, hunting trips, or slug rounds. The bristles are dense and stiff enough to tackle genuine fouling but won't damage the bore itself. If you're rotating between 12-gauge, 20-gauge, and .410 shotguns, a 16-gauge brush fills that mid-sized gap and gives you the right fit for proper contact and cleaning action.
Birchwood Casey has been grinding these out for decades because the formula works: nylon bristles, proper gauge sizing, and a brush that lasts. Keep one on your cleaning rod and you'll use it regularly enough to justify the small investment.

Frequently Asked Questions
Will this brush work on my shotgun?
This is a 16-gauge brush, so it's sized for 16-gauge shotgun bores. If you shoot a different gauge, you'll need a brush matched to that specific bore diameter for proper cleaning contact.
How does nylon compare to brass for bore cleaning?
Nylon bristles return to their original shape after use, maintaining consistent brush density and contact over many cleaning sessions. Brass can splay and become less effective with repeated use.
What kinds of fouling does this brush remove?
The dense nylon bristles are designed to scrub away carbon buildup, lead, copper residue, plastic wad material, and powder fouling from the bore.
Can I use this brush with my cleaning rod?
Yes, this is a standard bore brush designed for use with a shotgun cleaning rod. It screws onto the rod handle for thorough multi-directional scrubbing action inside the bore.
