Description
The Breakthrough Clean Phosphor Bronze Chamber Brush is a purpose-built chamber and bore cleaning tool designed for .223 Remington / 5.56mm NATO AR-15, M16, and M4 modern sporting rifles. It is engineered to attack residual carbon build-up in the chamber without damaging the bore steel, making it an essential part of any routine AR-platform cleaning kit.
This brush features durable phosphor bronze bristles mounted on a twisted brass core that keeps the brush rigid during use and delivers a deeper cleaning action than standard nylon brushes. The stiff bronze bristles scrub heavy carbon, copper fouling, and debris from hard-to-reach chamber surfaces, helping maintain reliable function and accuracy over extended shooting sessions.
The brush uses a standard 8-32 thread pattern for compatibility with virtually any standard cleaning rod handle, and its compact 3″ brush length makes it easy to maneuver through the chamber. Sold individually as a single chamber brush ready to drop onto your existing cleaning rod.
