Bore Tech Proof Positive Nylon Rifle Bore Brush 416 Caliber 10mm 8-32 Threads 3PK

Overview

Bore Tech Proof Positive Nylon Bore Brushes are designed for effective barrel cleaning without the risk of false copper fouling indications. Unlike phosphor bronze brushes, these 100% nylon brushes are copper-free, making them ideal for use with aggressive copper-removing solvents. They feature a double-wound, non-brass alloy core with a looped end, an aircraft-grade aluminum stud, and 8-32 male threads. The brushes contain double the standard amount of bristles for increased scrubbing action. For .17 and .20 caliber versions, the brush length is shortened to 1 inch to minimize cleaning rod flex.
