Otis FG330NB 7.62mm/.30 Cal Bore Brush Set Bronze/Nylon 8-32 Thread

The Otis FG330NB bore brush set delivers thorough barrel cleaning for popular .30 caliber rifles through its dual-bristle design. This 2-piece set handles 7.62mm NATO, .30-06 Springfield, .30-30 Winchester, .308 Winchester, and .300 caliber firearms with precision-engineered bronze and nylon bristles that remove fouling without damaging rifling.

What Makes This Different

The dual-material construction combines bronze bristles for stubborn copper fouling with softer nylon bristles for powder residue removal. Unlike single-material brushes that either scratch barrels or fail to remove tough deposits, this system provides complete cleaning action. The 8-32 thread pitch ensures compatibility with most cleaning rod systems, while the 2-inch brush length covers standard rifle bore dimensions efficiently.

Key Features

• Dual bronze and nylon bristle construction for complete fouling removal
• 8-32 thread pitch fits standard cleaning rods and bore guides
• 2-inch brush length optimized for rifle bore cleaning
• Compatible with 7.62mm NATO, .30-06, .30-30, .308 Win, .300 calibers
• Two brushes per package for extended service life

Field testing shows these brushes effectively remove carbon buildup and copper fouling that degrades accuracy over time. Competition shooters rely on this dual-bristle system between match stages, while hunters use them for seasonal maintenance. The bronze bristles cut through metal fouling deposits, while nylon bristles sweep away powder residue without scratching chrome-lined or match-grade barrels. Both materials resist shedding and maintain their cleaning effectiveness through hundreds of passes.
