Otis premium bore brushes will give you many times the life of most brushes due to the superior construction.

They have engineered features such as a precision thread with no weak undercut.

These brushes have a corrosive resistant Tufcor proprietary core wire with a tighter twist for better bristle retention, and can be used with all firearm cleaning chemicals.

Otis premium bore brushes also have twice the fill as other brushes, the stem is cold welded to the core, and the brushes are filled to the end.

Each brush features the size stamped on the stem and color-coded core wire to easily identify the brush size; this means that you will never clean your gun with the wrong brush.
