Otis FG345NB Bore Brush Set .44/.45/.458 Cal Bronze/Nylon 2-Pack

The Otis FG345NB Bore Brush Set delivers professional-grade cleaning performance for large caliber firearms with dual-material bristle construction. This 2-piece set handles multiple calibers from .44 Magnum to .458 Winchester, providing shooters with versatile cleaning capability in one package.

What Makes This Different

The hybrid bristle design combines bronze and nylon materials to tackle both fouling types effectively. Bronze bristles remove stubborn copper and lead deposits while nylon bristles provide gentle scrubbing for powder residue without damaging rifling. The 8-32 thread pitch ensures compatibility with standard cleaning rods, while the 2-inch brush length provides optimal contact surface area for thorough bore cleaning.
