With Otis' All Purpose Receiver Brushes you'll have the right brush for the right project. These brushes are the best for cleaning those hard to reach places. They can scrub places where carbon, powder, and copper residue hibernate. Brushes are available in a variety of tolerances. The softest is the nylon bristled brush, followed by a slightly more aggressive blue nylon bristled brush. The most aggressive of Otis' All Purpose Receiver Brushes is the bronze bristled brush.
This package includes three each of the Nylon, Stainless and Bronze brushes for a total of nine brushes.
