B/C Nylon Bore Brush 40/41/10Mm Red

A Birchwood Casey nylon bore brush in .40/.41/10mm is a straightforward cleaning tool for shooters who maintain their own firearms. These brushes are built with dense red nylon bristles that scrub away carbon buildup, lead, copper fouling, and plastic wad residue without damaging bore walls. The nylon construction means the bristles flex under pressure and return to shape after each use—no permanent deformation from hard scrubbing, which keeps the brush effective through dozens of cleaning sessions.

If you're running semi-auto pistols or revolvers in these common calibers, this brush fits standard jag attachments and works with any cleaning rod you already own. The stiff bristle design tackles stubborn fouling in a way softer brushes can't, but nylon won't scratch or score like brass or steel would. It's a no-frills, affordable part of a solid bore-cleaning routine.

Birchwood Casey bore brushes have been a staple in gun cleaning kits for decades—they're not fancy, but they work. Keep one in your range bag or cleaning kit and replace it when the bristles start to fray, which typically takes longer than you'd expect given the price.
