The harpoon and barrel brushes are special brushes used in the cleaning and maintenance of firearms. They effectively clean the lead, gunpowder residue and other dirt accumulated in the barrel, extending the performance and life of the weapon. These brushes, produced in various calibers, are made of durable materials such as stainless steel, bronze or nylon. These brushes, which are manually used by attaching to the harpoon bar, are indispensable parts of regular weapon maintenance. They provide safe and effective use by cleaning without damaging the sensitive parts of the weapon.
