Hoppe's 5.56mm/.223 Rem AR Chamber Brush

The Hoppe's 5.56mm/.223 Rem AR Chamber Brush (Model 1323P) is a precision cleaning tool designed for the AR-15 platform and other rifles chambered in 5.56mm or .223 Remington. This chamber brush effectively reaches deep into the bolt carrier group area and chamber neck, removing carbon fouling, powder residue, and copper buildup that standard bore brushes cannot access. Proper chamber maintenance is crucial for extending barrel life and ensuring consistent ignition during high-volume shooting sessions.

The brush features robust construction optimized for the geometry of 5.56mm chambers, where carbon accumulation can be significant. Its dimensions allow it to navigate the tight confines of an AR-15 upper receiver without binding. The bronze bristles are stiff enough to dislodge stubborn deposits while being gentle enough not to damage chamber walls or the bolt face when used correctly with a cleaning rod and solvents.

This brush is essential for AR operators, law enforcement patrol rifle units, and competitive shooters who maintain tight accuracy standards. After high-round-count training days or duty fire, chamber fouling can affect bolt seating and primer pocket cleanliness—two critical variables for reliability and shot-to-shot consistency. The Hoppe's 5.56mm/.223 Rem AR Chamber Brush is a reliable addition to any field cleaning kit or range bag.
