Birchwood Casey Nylon Bore Brush .223/5.56 – MSR Cleaning

This nylon bore brush is purpose-built for .223 Remington and 5.56 NATO chambered MSRs (Modern Sporting Rifles).

The brush threads onto standard cleaning rods and is color-coded red for quick caliber identification in your cleaning kit. Designed for AR-15 pattern rifles and other firearms chambered in .223/5.56.
