Otis 41CAL Bore Brush

Precision thread with no weak undercut. Brushes have a Tufcor proprietary core wire that is corrosive resistant, has a tighter twist for better bristle retention and can be used with all firearm cleaning chemicals. Stem is cold welded to the core and 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.SPECIFICATIONSModel Body CopyBrush #40 for .40, .401, .404, .405, .41, 10M
