Pro-Shot Chamber Maid Bow Tie Swab Features The Pro-Shot Chamber Maid Bow Tie Swab is purpose-built to clean locking lug recesses an area of the action that standard bore brushes and patches often fail to fully reach. The patented full locking lug design covered under US Patent number 0562 935 conforms to the shape of the locking lugs to remove carbon and fouling buildup that accumulates after repeated firing. Made from strong absorbent industrial wool felt the swab holds enough CLP or oil to apply lubrication evenly across the locking lug surfaces during cleaning. This targeted design helps keep the bolt cycling smoothly and reduces wear in an area that is easy to neglect during routine maintenance. Each swab threads onto a standard .30 caliber bore brush with a nylon bristle brush recommended for the best fit and performance. This threading system makes the swab compatible with cleaning rods shooters likely already own avoiding the need for specialized tools. The design is particularly useful for bolt action rifles such as the Model 70 M77 Mark II CZ 550 Savage 110 Sako and Tikka all of which benefit from dedicated locking lug cleaning. Sold in a 20-count pack and made in the USA these Chamber Maid swabs give shooters a simple effective way to extend the service life and reliability of their bolt action rifle s action.
