Ar-15/m16 Chamber Brush 8-32m Threads

The AR-15/M16 Chamber Brush with 8-32 threads is a precision cleaning tool designed for shooters and armorers who demand reliability in firearm maintenance. Chamber fouling—carbon buildup, powder residue, and copper deposits—degrades accuracy and can contribute to pressure anomalies over time. This brush addresses that problem directly, reaching into the chamber and bolt face areas where standard bore cleaning cannot access effectively.

This chamber brush features 8-32 male threads, the standard interface for most AR-15 and M16 cleaning rod systems, allowing seamless integration with your existing maintenance kit. The brush construction uses brass bristles—softer than steel, preventing damage to hardened chamber walls while delivering aggressive cleaning action on stubborn deposits. The compact, lightweight design (0.02 lbs) makes it portable for field stripping and cleaning operations, whether at the range, in the field, or in the armory.

This tool is essential for AR-15 and M16 owners seeking accuracy assurance and consistent ignition, particularly those running high-round-count practice or duty cycles. Law enforcement and military personnel rely on chamber brushes during routine maintenance cycles to ensure consistent round-to-round performance and extend barrel life. Brownells' manufacturing ensures consistent bristle density and thread concentricity, eliminating wobble during use and delivering uniform contact pressure throughout the chamber.
