Kleen-Bore A161 Bore Brush 28 Gauge Shotgun 5/16-27 Thread Phosphor Bronze

The Kleen-Bore A161 is a dedicated 28 Gauge shotgun bore brush built to scrub fouling, wad residue, and powder buildup from shotgun bores without scoring the steel. It is part of Kleen-Bore's long-running line of gauge- and caliber-specific brushes, each cut to the correct core diameter for its chambering so the bristles make full contact with the bore wall.

The brush uses phosphor bronze bristles with rounded bristle tips, a classic bore-cleaning material prized for its balance of scrubbing action and gentleness on barrel steel. Phosphor bronze breaks up copper and powder fouling efficiently while remaining safe for routine use on modern shotgun bores. The brush is mounted on the standard American shotgun 5/16-27 thread pattern, which fits the vast majority of U.S.-made cleaning rods, jags, and handles.

To use, apply your preferred solvent, run the brush through the bore in a single direction following the bore, and follow up with patches and a bore mop until the patches come out clean. The A161 is sized specifically for 28 Gauge shotguns and is equally useful for cleaning fixed chokes and removable choke tubes. Made in USA.
