Pro-Shot 20STO Tornado Bore Brush 20 Gauge Shotgun #5/16-27 Thread Brass Spiral Wound Loop

The Pro-Shot 20STO Tornado Bore Brush is a purpose-built 20 gauge shotgun cleaning brush featuring Pro-Shot's signature brass spiral-wound loop design. Often referred to as "The Gunsmith's Brush," the Tornado replaces conventional bristle tips with continuous brass loops that scour fouling out of the bore without leaving loose bristle ends behind and without scoring or damaging rifling.

Cut to 20 gauge size, this brush is highly effective at removing heavy fouling, wad buildup, and stubborn powder and lead residue from shotgun bores. The brass spiral-wound construction rides the bore with consistent, full contact, making it a go-to choice for gunsmiths and shooters who need reliable, non-abrasive cleaning on smoothbore and rifled shotgun barrels alike.

The brush features a standard #5/16-27 thread that fits the common shotgun cleaning rods and rod handles already in most benches and range bags. Sold as a new single brush, the 20STO drops straight into your existing cleaning setup.
