For users or customers possessing firearms with high precision or performance, the marginal additional expense of our special line brushes is justified to prevent any risk of the cleaning brush's shank scratching the critical barrel. The brass shank is constructed as a single, looped and wound piece, rather than two twisted pieces that are cut off. The coupling is made of non-scratch brass. The bristles are composed of premium phosphor bronze scrubbing wire, ensuring durability and effective cleaning.

• Phosphor bronze bristles, known for their superior conductivity and corrosion resistance, are engineered to optimize performance in demanding electrical and mechanical applications
