Breakthrough Clean BT40BM Bore Mop for .40/10mm Firearms - Premium Gun Cleaning Accessory

A bore mop is one of those cleaning tools that makes a real difference in how effectively you can clean the inside of your barrel. The Breakthrough Clean BT40BM Bore Mop for .40/10mm firearms is designed specifically for pistol calibers that share the same bore diameter, giving you a mop that fits properly and does the job without slipping or binding. Whether you shoot .40 S&W, 10mm Auto, or both, this mop works well as part of a regular maintenance routine to help keep your bore in good shape.

Breakthrough Clean Technologies builds gear that shooters actually use—no fancy marketing, just functional tools. A bore mop complements wet patches and brushes in your cleaning kit, letting you run a solvent or oil through the bore to help loosen fouling and push out debris. It's the kind of accessory that lives in your range bag and earns its keep on shooting days and during deep cleaning sessions at home.

If you run .40 or 10mm pistols regularly, having the right-sized mop matters. Too loose and it won't contact the bore properly; too tight and you'll wrestle with it. The BT40BM is cut for the bore diameter of these calibers, so it fits the way it should. Pair it with your favorite solvent, a brass brush, and patches, and you've got the core of a solid bore-cleaning routine.

Frequently Asked Questions

Will this bore mop fit my .40 S&W and 10mm pistols?

Yes. The BT40BM is sized for both .40 S&W and 10mm Auto, which share the same bore diameter. It will fit properly in either caliber.

What's the difference between a bore mop and a bore brush?

A bore brush has stiff bristles designed to scrub and dislodge fouling; a bore mop has softer, looser fibers that work better for pushing solvent through the bore and mopping up loosened debris and residue. They're complementary tools in a complete cleaning kit.

How do I use a bore mop?

Attach it to your cleaning rod, soak it in your preferred solvent, and run it through the bore several times. It helps distribute solvent evenly and push out fouling that brushes have loosened. Follow up with dry patches to remove excess solvent and residue.
