OTIS brushes last longer than most because of their superior construction and engineered features. The precision thread has no weak undercut. The Tufcor proprietary core wire resosts corrosion. The tighter twist provides better bristle retention. These brushes can be used with all firearm cleaning chemicals. They have twice the fill as other brushes, the stem is cold welded to the core, and the brushes are filled to the end. The brush size is stamped on the stem and the core wire is color coded so you never clean your gun with the wrong brush. The rifle bulk brushes come in a reusable snap pack case.
