KleenBore A177N Nylon Bore Brush .22/.223/5.56mm 8-32 Thread

The KleenBore A177N bore brush delivers thorough cleaning for .22 caliber, .223 Remington, and 5.56mm NATO rifles without the aggressive scraping of bronze brushes. This nylon-bristled cleaning tool removes fouling and debris while protecting barrel rifling from unnecessary wear during routine maintenance.

What Makes This Different

Unlike traditional bronze brushes that can gradually wear barrel steel, the A177N features dense nylon bristles that effectively scrub carbon buildup and powder residue without metal-on-metal contact. The 8-32 thread pitch ensures compatibility with most standard cleaning rods, while the precisely sized brush diameter matches .22/.223/5.56mm bore specifications for optimal cleaning contact. This design extends barrel life compared to more abrasive alternatives.

Key Features

• Nylon bristles protect barrel rifling from wear during cleaning
