Pro-Shot Chamber Star Swab Features The Pro-Shot Chamber Star Swab is engineered around a patented full AR lug recess pattern US Patent #0 562 935 that matches the geometry of the locking lugs found in 5.56mm and .223 Caliber chambers. This shaped design lets the swab apply CLP or oil evenly across every recess then pull loosened fouling and carbon out of corners a standard bore brush alone cannot reach. The swab threads directly onto a standard 5.56mm/.223 Caliber bore brush and Pro-Shot recommends a nylon bristle brush for the best combination of scrubbing action and surface protection. Because the pattern is purpose built for the AR platform shooters get a more complete chamber cleaning in less time than improvising with cotton patches or cloth. Each swab is made from strong absorbent industrial wool felt that holds solvent and lifted fouling without falling apart mid-stroke standing up to repeated passes during a thorough cleaning session. The 20 pack format means AR owners always have fresh swabs on hand rather than reaching for a worn-out one that has already picked up more carbon than it can hold. Pro-Shot manufactures the Chamber Star Swab in the USA reflecting the company s long-standing focus on American-made firearm cleaning tools. Whether maintaining a single home-defense carbine or servicing a rack of range rifles this pack gives shooters a reliable purpose-built way to keep chambers running clean for sale at GrabAGun.
