Birchwood Casey MSR Chamber Brush .223/5.56mm

The Birchwood Casey MSR Chamber Brush is a dedicated chamber cleaning tool designed specifically for .223 Remington and 5.56mm NATO rifle chambers. Its stiff bronze bristles scrub carbon, powder residue, and fouling from the chamber walls and locking lug recesses where standard bore brushes can't reach. Regular chamber cleaning prevents extraction issues and maintains reliable feeding in AR-15 and MSR platforms.

This brush features durable bronze bristles that effectively remove stubborn deposits without damaging chamber surfaces. The 8-32 thread attaches to standard cleaning rods. Designed for the unique geometry of AR-15/MSR chambers, it reaches areas that accumulate heavy fouling during high-volume shooting.
