BoreTech Bronzový spirálový kartáč na brokovnice 20GA

BoreTech BTSB-20-100 is a spiral (tornado) cleaning brush designed for 20 GA shotguns. It uses wound phosphor-bronze bristles that increase the contact area within the bore and allow effective removal of carbon and plastic residue from shotgun shells.

The brush design is engineered for high efficiency and longer service life compared to standard wire brushes, while remaining gentle on the barrel bore when used correctly.
