Pro-Shot Chamber Maid 5.56 Chamber Cleaning Swabs 20 Pack

Carbon builds up in a 5.56 chamber and the throat ahead of it, and a patch running straight through the bore never wipes any of that area. These swabs are made for chamber work: run one on a rod after a chamber brush and turn it so the felt picks up what the brush loosened.

Twenty swabs to a pack. Keeping the chamber clean is what keeps extraction consistent on a rifle that gets run hard, and it adds about a minute to the end of a cleaning session.
