Birchwood Casey 41246 7mm Bronze Bore Cleaning Brush

The Birchwood Casey 41246 is a bronze bore cleaning brush cut to fit 7mm (.284 caliber) rifle bores. Built around a sturdy steel core tipped with bronze bristles, this brush threads onto any standard cleaning rod with a 8-32 thread pattern and delivers thorough, multi-directional scrubbing action from chamber to muzzle.

Bronze is gentle on barrel steel but aggressive on the fouling that actually costs you accuracy: copper, lead, and carbon buildup. The stiff bristles work loose hard-deposited fouling so your patches and solvent can lift it out, helping restore consistent groups and clean shot strings. Sized for the .284/7mm bore, it is a staple consumable for routine rifle maintenance and a standard addition to any gun cleaning kit.

Best practice is to wet the brush with a quality bore solvent, run it one direction through the bore the same number of strokes each pass, and follow with clean patches until they come out white. The 8-32 thread is the standard fitment for most quality one-piece and sectional cleaning rods on the market, so this brush drops right into most existing cleaning setups. Made by Birchwood Casey, a long-trusted name in firearm cleaning and shooting accessories.
