A product every 10/22 owner should own! Like many semi-automatic rimfire rifles, the 10/22 is impossible to clean from the breech end with regular cleaning rods and brushes. Cleaning from the muzzle is an option, but that pushes oils, solvents and carbon fouling from the barrel into the action. The Possum Hollow Cleaning Clip installs just like a factory Ruger magazine, catching dirty patches, solvents and oil pushed out of the barrel as you clean. It also acts as a positive stop for the cleaning rod, eliminating the possibility of damage to the bolt face. Durable polymer construction cleans up easily.
