I really like the Otis cleaning kits. They use a flexible coated cable to pull a brush or patch through the bore. I havethe one called the'Tactical kit' which can clean anythign from a .17 to a 12 guage shotgun and the whole kit is about the size of my fist.Supposedly, the cable can be used to punch obstructions out of the bore, though I've never tried it or seen it done myself.
