Keep your shotgun in peak shooting condition with the Pro-Shot Tornado Bore Brush 20STO, the professional’s choice for deep, effective, and safe bore cleaning. Specially designed for 20 gauge shotguns, this brass spiral-wound loop brush provides unmatched cleaning efficiency while protecting your barrel from scratches, wear, and damage. Whether you’re maintaining your favorite upland hunting shotgun or your competition scattergun, Pro-Shot’s Tornado Bore Brush guarantees superior cleaning performance every time.
Professional-Grade Design for Maximum Cleaning Power
The Pro-Shot Tornado Bore Brush is not your ordinary wire brush. Its innovative spiral-wound design features tightly wound brass coils that form continuous cleaning edges, delivering a scrubbing action that effectively removes lead, plastic wad fouling, powder residue, and carbon buildup without being overly abrasive.
Unlike standard wire brushes that use sharp bristles, the Tornado’s rounded loops gently polish the bore surface while maintaining its integrity — ensuring your shotgun barrel stays clean, smooth, and free from scoring.
The result is a deep, thorough clean with minimal effort — perfect for hunters, clay shooters, and gunsmiths who demand professional results.
Safe and Effective for All 20 Gauge Shotguns
Engineered specifically for 20 gauge bores, the Pro-Shot 20STO brush delivers a perfect fit for optimal cleaning contact along the entire barrel. It’s ideal for maintaining pump-action, semi-automatic, over/under, and single-barrel 20-gauge shotguns.
The brass spiral-wound filaments are softer than steel yet tough enough to remove stubborn fouling, ensuring a safe cleaning process that won’t harm chrome-lined or blued finishes. You can use it confidently on high-end shotguns without worrying about scratching or damaging the bore.
Built to Last — Premium Brass Construction
Durability is at the core of every Pro-Shot Tornado Brush. Made from high-quality brass filaments and precision-wound for consistency, the 20STO resists deformation and bristle breakage, even under heavy use.
The brass loop ends ensure structural integrity and safe operation during cleaning, while the solid #5/16-27 threaded base fits most standard shotgun cleaning rods. This means it’s fully compatible with your existing Pro-Shot or industry-standard cleaning tools, making it a perfect addition to any shooter’s cleaning kit.
