Birchwood Casey 41242 Bronze Bore Cleaning Brush .22/.223/5.56mm

The Birchwood Casey 41242 is a bronze bore cleaning brush built to scrub fouling from .22 caliber rifle bores, and it also fits .223 Remington and 5.56mm NATO chambers. The bronze bristles deliver a thorough multi-directional scrubbing action that returns to its original shape after use, making the brush both durable and reusable across many cleanings.

Designed for routine bore maintenance, this brush is tough on copper, carbon, and lead fouling while remaining gentle on barrel steel. A steel shank forms the rigid core that drives the bristles evenly down the bore, and the standard 8-32 thread pattern threads onto virtually any quality cleaning rod so it drops right into most rifle cleaning kits.

Whether you are maintaining a .22 caliber rimfire, working up loads for a .223 Rem, or keeping a 5.56mm carbine clean, the Birchwood Casey 41242 bronze brush is a reliable go-to for keeping bores clean and accurate. Use it with your preferred solvent and follow up with patches for a complete cleaning pass.
