Like the “Comfort” version made of wool felt, but with “soft” brass fibers integrated into the felt for intensive mechanical cleaning. Removes combustion residues from fields and trains, dissolves lead deposits and also provides mechanical support during chemical cleaning. Due to its high storage capacity, it is suitable for applying or removing oils, running cleaner pastes, etc. Since the brass is much softer than the barrel steel, the cleaners can be pulled through the barrel without leaving any injuries inside the barrel.
