I have several cleaning kits with rods but what I like and use most is the Otis cleaning system that uses coated SS cable with brass fittings for .17-.50 caliber. The Otis cables clean by pulling from breach to muzzle which lessens the chance of crown damage that can result from using rods at the muzzle end. It's especially useful for .22s, M1 Garands and M1As.
