Otis FG322NB Bore Brush Set 5.56/.223/22 LR Bronze/Nylon 8-32 Thread

The Otis FG322NB Bore Brush Set delivers precision cleaning for multiple calibers with dual-bristle technology that removes fouling without damaging rifling. This professional-grade cleaning solution combines bronze bristles for carbon removal with nylon bristles for final polishing in one convenient package.

What Makes This Different

Unlike single-material brushes that either scratch bores or fail to remove stubborn carbon, the FG322NB features dual-bristle construction optimized for multi-stage cleaning. The bronze bristles cut through copper fouling and carbon buildup while nylon bristles provide gentle final cleaning without metal-on-metal contact. This combination reduces cleaning time by 40% compared to using separate brushes for each cleaning stage.

Key Features

• Dual bronze and nylon bristle construction for complete fouling removal
• Compatible with 5.56mm NATO, .223 Remington, .22 LR, and .22-250 calibers
• Standard 8-32 threading fits most cleaning rod systems
• 2-inch bristle length provides full bore contact in standard barrels
• Two brushes per package for extended cleaning sessions
• Corrosion-resistant bronze alloy bristles maintain stiffness over time
• High-density nylon bristles won't shed or break during use

Field testing demonstrates effective carbon removal in as few as 10 passes through the bore, significantly reducing solvent requirements and cleaning time. The bronze bristles maintain their aggressive cleaning properties through hundreds of cleaning cycles, while the nylon component ensures no scratching occurs on precision match barrels. Competition shooters report consistent accuracy maintenance when using this brush system between matches.
