Super-aggressive, extra-stiff, heavy weight nylon bristles effectively clean stubborn bore deposits without damaging rifling or smoothbore surfaces.
Constructed with a strong, one-piece brass shank and coupling to prevent scratching the bore, enhancing the durability of the brush.
Designed specifically for 20 Gauge shotguns, this 12 pack of brushes is compatible with solvents and features a 2-7/8" overall length with a 5/16"-27 thread.
