Pro-Shot Chamber Maid 5.56/.223 Chamber Star Swabs, 20-Pack

The Pro-Shot Chamber Maid Chamber Star Swab (brand part no. 556CMS-20) is a patented tool built to clean the locking lug recesses of an AR-platform rifle chambered in 5.56mm/.223, an area a standard bore brush can’t reach. It threads onto your existing bore brush, and rotating it inside the star chamber breaks loose and removes carbon and fouling buildup that accumulates in the lug recesses. Sold 20 to a pack, there’s enough on hand to keep a home cleaning bench or a shop running for a long time. See the full Pro-Shot lineup in our gun cleaning kits and supplies category.
