Otis Technology 5.56mm Chamber Brush – AR-15/M16 Cleaning Tool

The Otis Technology 5.56mm Chamber Brush is purpose-built to scrub carbon and fouling from the chamber and locking lug recesses of AR-15 and M16 rifles. Its stiff nylon bristles reach into tight areas that standard bore brushes miss, breaking up baked-on residue that can cause extraction failures and accuracy issues. This specialized brush attaches to most cleaning rods and cable systems, making it a practical addition to any AR maintenance kit.

Designed specifically for the 5.56x45mm NATO/.223 Remington chamber dimensions, this brush features durable construction that holds up to repeated use with standard cleaning solvents. The bristle pattern cleans the chamber walls and star chamber area without scratching or damaging the bore extension.
