Breakthrough Clean Phosphorus Bronze BCG Brush 3" #8-32 Thread

The Breakthrough Clean Phosphorus Bronze BCG Brush is a purpose-built scrubbing tool designed to strip carbon, fouling, and debris from bolt carrier groups. At 3" long with a standard #8-32 thread, it mates to most common cleaning rods and T-handles already on your bench.

The brush uses phosphor bronze bristles wrapped around a twisted brass core. The rigid brass core keeps the brush from folding or splaying under pressure, while the bronze bristles deliver a deeper scrubbing action than nylon without scoring the hardened steel surfaces of your carrier. It is a go-to geometry for fouled bolt, gas key, and carrier body cleanup on the AR platform.

Designed for routine AR-15 platform maintenance, this brush lets you work the bolt, gas key, and carrier body clean quickly and consistently. One per package.
