BoreSmith, Gauge 12, Shotgun Bore Brushes, 10-Pack, Phos Bronze

We use core wires made out of carbon steel because carbon steel is not only stronger than other metals, making it more resistant to bending, but also carbon steel core wires grip bristles tighter. Buying our quality brushes in bulk packs saves you a lot of money. Our low unit price plus shipping through Amazon is less than gas money spent to drive to a store 30 minutes away.

Our standard brushes have phosphor bronze filaments, and they are made for shotgun length chambers
Standard 5/16-27 threaded connectors are made of non-abrasive aluminum
Carbon-steel twisted core wires give our brushes superior strength that resists bending
Comes packed in clam shell for safe and easy storage
Phos bronze filaments clean with more friction than nylon filaments do
