Otis Products Inc. Pop Canister Of Rifle/Pistol Brushes .40 Cal - 100 Ct
The Otis Technology Pop Canister of .40 caliber rifle and pistol brushes brings a no-nonsense approach to firearm maintenance. This 100-count pack of .40 cal brushes is built for shooters who demand reliability in every cleaning session—whether you're breaking in a new handgun, maintaining a service pistol, or keeping your .40 S&W hunting or competition rifle in top condition. With 100 brushes in the canister, you'll have plenty on hand for regular cleaning without running dry mid-session.
What sets these brushes apart is their construction. Each brush features a brass core that's cold-welded to the stem—a manufacturing method that eliminates the loosening, corrosion, and breakage you'd get from cheaper alternatives. The core won't strip threads or damage bore walls, and the folded bristle design runs all the way to the end, ensuring you're actually scrubbing carbon buildup and copper fouling in the bore, not just the top layer. Caliber markings stamped directly on the stem keep you from mixing sizes when you've got multiple guns in the safe.
Otis designed these brushes around precision tolerances. The threading is exact—no weak undercuts that fail under normal cleaning pressure—so you can apply real elbow grease without worrying about the brush coming apart mid-stroke. For shooters who clean their own guns (which is everyone serious about gun maintenance), having a reliable brush that lasts is as important as the solvent you're using.

Frequently Asked Questions
Will these .40 cal brushes work with my .40 S&W pistol?
Yes. These brushes are designed for both rifle and pistol cleaning in .40 caliber, so they're compatible with .40 S&W handguns and any rifle chambered in .40 cal.
What's the advantage of the cold-welded construction?
Cold-welding bonds the brass core directly to the stem without heat, creating a more durable connection that won't loosen, corrode, or fail under cleaning pressure. This keeps the brush intact through many cleaning sessions.
How many brushes should I expect to use per cleaning?
That depends on how fouled your bore is and how thorough you are, but most shooters use one brush per complete cleaning cycle. With 100 in the canister, you'll have ample supply for regular maintenance without needing to reorder frequently.
Will the bristles damage my gun bore?
No. The brass core is specifically chosen because it's softer than steel, so it won't scratch or harm your bore. The folded bristle design provides aggressive scrubbing action without abrasiveness.
