The Otis 5.56mm Chamber Brush is purpose-built to scrub carbon and fouling from the hard-to-reach chamber and locking lugs of your 5.56mm rifle. Combining a brass brush section with a stiffer steel brush segment, it delivers focused cleaning where standard bore brushes cannot reach, helping maintain reliable function and smoother cycling.

This compact accessory is ideal for routine range maintenance, training days, and general rifle care whenever you need to keep your chamber clean between full tear-downs. Designed to work with compatible cleaning rods and kits, it offers a simple way to extend the life of your firearm and preserve consistent performance. Backed by Otis’s reputation for thoughtful, shooter-focused cleaning solutions, this chamber brush is a practical addition to any 5.56mm rifle kit.
