fwiw, I've went through a few Otis kits until I realized all I needed was the cable out of the kit. I went to amazon and purchased 6 Otis Micro kits. Now when I clean, I stage all 6 and it speeds up cleaning by just pulling them all through one at a time. (with whatever lube/cleaner I plan on using). I think I purchased each kit for about $12-13 shipped. I put all 6 cables w/ patch already rigged up in a zippered case for a mouse. (also holds the lube) The small kits have a different thread for brushes but I usually use a bore guide if I let my firearm get that dirty.
