Iosso Eliminator Bore Brush - 20 ga

The Iosso Eliminator Bore Brush for 20 gauge shotguns is a purpose-built cleaning brush engineered for serious shooters and tactical operators who demand superior fouling removal. Unlike traditional brass or bronze brushes, the Iosso Eliminator features a proprietary cobalt blue fiber construction that is wound tighter with greater density per inch, allowing aggressive back-and-forth scrubbing action without bristle damage. This 20 ga bore brush removes copper deposits, lead buildup, plastic wad residue, and powder fouling more effectively than conventional options, making it an essential component for maintaining shotgun bore integrity and accuracy.

The stiffer, higher-density fiber design outperforms standard brass or bronze brushes in both durability and cleaning power. The distinctive cobalt blue color prevents accidental cross-contamination with other brush types in your cleaning kit. The 20 gauge Eliminator brush is engineered to work synergistically with Iosso Bore Cleaner and Triple Action Solution, a combination that addresses the full spectrum of shotgun fouling—from powder residue to copper and lead deposits. The brush withstands multiple cleaning cycles before requiring replacement, delivering better value than disposable alternatives while maintaining consistent scrubbing performance throughout its service life.

This brush is suited for hunters, clay shooters, law enforcement officers with shotgun responsibilities, and shooters maintaining patrol or home-defense firearms. 20 gauge shotgun operators—particularly those firing volume through competition, training, or duty cycles—benefit from more aggressive cleaning than softer brushes provide. The aggressive action capability makes the Iosso Eliminator ideal for removing stubborn plastic wad buildup and lead fouling that accumulates in defensive or sport shooting scenarios without requiring additional brush types.
