Advice for using the brushes
The metallic brush mainly targets carbon residues in your barrel. For optimal use, avoid using dry and use a specific technical product for carbon (Armistol 4-in-1 oil)
The nylon brush mainly targets copper residues with a powerful copper-removing action
The woollen brush is used to protect or dry the barrel. To increase the longevity of the brush, we recommend using it in conjunction with an oil.
