Iosso Eliminator Bore Brush - .40/.41

The Iosso Eliminator Bore Brush in .40/.41 caliber is purpose-built for shooters and law enforcement who demand deep bore cleaning action that standard brass and bronze brushes cannot deliver. Unlike traditional designs, the Iosso Eliminator features a proprietary cobalt blue fiber construction that enables aggressive back-and-forth scrubbing motion—the distinguishing characteristic that sets this bore brush apart from conventional spiral-wound tools. The fiber is wound tighter with greater density per inch, meaning each brush delivers more contact surface and longer service life before replacement becomes necessary.

The .40/.41 caliber sizing makes this brush compatible with mid-bore pistol and revolver applications in this diameter range. The stiffer fiber grade tolerates the aggressive back-and-forth scrubbing action that dissolves copper fouling, lead residue, plastic wad buildup, and carbon—contaminants that accumulate during high-round-count training sessions or duty carry. For maximum effectiveness, pair this brush with Iosso Bore Cleaner and Triple Action Solution, a proven system that chemically breaks down fouling while the brush's mechanical action removes it. The cobalt blue color provides instant visual identification, preventing accidental cross-contamination with brushes intended for other calibers.

This brush is favored by competitive shooters, law enforcement patrol officers, and range instructors who maintain firearms to exacting standards. The ability to reuse the brush multiple times before wear reduces long-term cleaning kit costs for high-volume shooters. Its durability under repeated scrubbing makes it particularly valuable for armory maintenance and duty weapon maintenance programs where consistency and efficiency matter.

Iosso Products has built a reputation in the firearms maintenance category for engineering brushes that outperform generic alternatives through superior fiber technology and manufacturing precision. The Eliminator line represents the brand's commitment to solving real bore fouling challenges that emerge during extended shooting sessions. Shooters who have transitioned from traditional brass brushes consistently report cleaner bores with less effort and faster cleaning cycles—measurable improvements in maintenance efficiency.
