These chamber cleaning brushes are designed to remove the burnt powder fouling which forms in the chamber of M1A, M14 rifles and M1 Garand rifles. Easy to use, apply solvent to the brush, push the brush into the chamber, close the bolt on the back of the brush, and rotate the brush with a punch or screwdriver in the ratchet holes of the brush. Pull back while ratcheting the brush to remove it. Mfg: Dewey
