KleenBore 20 Gauge — Phosphor Bronze Bore Brush
A professional-grade bore brush designed for safe, effective cleaning of 20-gauge shotguns. Constructed from phosphor bronze with straight (non-crimped) wires, this brush combines strong cleaning power with a gentle touch — removing fouling and powder residues without damaging the barrel or rifling. Its straight-wire construction maintains shape and stiffness under pressure, giving consistent performance even during heavy cleaning.
Why it stands out
Phosphor bronze bristles: aggressive on deposits but gentle on metal surfaces.
Straight (non-crimped) wires: superior cleaning action and long-lasting shape retention.
Won’t deform easily: holds its stiffness during tougher scrubbing, so you get uniform cleaning along the bore.
Safe for rifled or grooved bores: designed to clean effectively without harming coarse bore surfaces or rifling.
