I know there are probably hundreds of these out there but I wanted to post a pic of a pull through cleaner I made. It's pretty simple. I had some heavy braided fishing line (75-80 lb.) and cut about a 5.5 foot piece for the loop to pull the cleaning patch. I laid it alongside a piece of .080 trimmer line and secured it with short lengths of heat shrink tubing. I finished with a loop at the end to use to pull it from the muzzle end. It's flexible but still stiff enough to feed down the barrel (using soda straw to clear the moderator) until it comes out the loading port. Loop a couple of patches through the string loop and pull back through the barrel to clean, dry and oil.
