Kleen-Bore A184 20 Gauge Bore Cleaning Brush

The Kleen-Bore A184 20 gauge bore cleaning brush is a shotgun maintenance essential for anyone serious about keeping their scattergun in fighting trim. Built from phosphor bronze, this brush is engineered to scrub away powder fouling and combustion residue without compromising the integrity of your barrel. The straight wire bristles—not the crimped kind—deliver aggressive cleaning action where you need it, and they're tipped with a rounded profile that respects the bore's geometry while you work.

What sets this 20 gauge shotgun cleaning brush apart is its durability under pressure. The phosphor bronze construction stays thick and stout; it won't collapse or bend easily as you push it down the bore, which means it keeps its cleaning geometry and won't leave bristles behind. That's a real difference when you're running a brush repeatedly through a tight bore. Phosphor bronze is the material of choice here because it cleans hard without etching or scoring the steel—especially important for maintaining the bore's internal finish over years of use.

Threaded to American standard shotgun spec (#5/16-27), the A184 fits the cleaning rods and handles you already own. Made in the USA, it's a no-nonsense tool built to last, whether you're field-stripping after a day in the marsh or doing post-season deep cleaning.

Specifications

Frequently Asked Questions

Is this brush compatible with my cleaning rod and handle?

Yes, if your cleaning rod uses American standard shotgun threads (#5/16-27), this brush will screw on directly. Check your rod's thread specification to confirm compatibility.

Will a phosphor bronze brush damage my shotgun barrel?

No. Phosphor bronze is softer than steel barrel material and is specifically chosen to remove fouling and powder residue safely without scoring or etching the bore's internal finish. The rounded bristle tips add an extra margin of protection.

What makes straight bristles better than crimped ones?

Straight bristles maintain their shape and cleaning geometry as they work down the bore, delivering more consistent scrubbing action and more effective removal of stubborn fouling compared to crimped designs that can compress or splay unevenly.

Can I use this brush for other gauges?

This brush is made for 20 gauge shotguns. Using it in a different gauge may result in an improper fit or cleaning performance. Use a brush matched to your specific gauge.
