Brownells Cotton Bore Mop 40 Caliber 12 Pack

The Brownells Cotton Bore Mop 40 Caliber 12 Pack delivers reliable cleaning power for your rimfire and centerfire .40-caliber rifles and handguns. Cotton bore mops are a proven cleaning essential—the natural fibers absorb solvents and oils effectively, then work with the gun's bore to scrub away loosened powder fouling during the patch-and-solvent phase of routine maintenance. Whether you're breaking in a new barrel, deep-cleaning after a hunting season, or performing regular upkeep, these mops handle the wet work so you can focus on getting your bore truly clean.

Cotton's absorbent nature makes it ideal for applying bore-conditioning products like Brownells Moly Bore Paste or J-B Compound, which many shooters use to speed break-in or address stubborn fouling. The 12-pack ensures you won't run out mid-cleaning session and makes it easy to keep a fresh mop on hand for each step of your cleaning routine.

For hunters, competitive shooters, and anyone who takes barrel maintenance seriously, bore mops are a simple, inexpensive way to improve your cleaning results. Stock a pack in your range bag or cleaning kit and you'll always have one ready when you need it.
