Pro-Shot's Dual purpose design chamber mop can clean and lubricate both the chamber and locking lug recesses of your AR15/M4/M16 platform rifle. The longer smaller part of the mop reaches the chamber area, while the larger diameter is meant to reach the star chamber/ locking lug recess area. Excellent for use after bristled chamber brush for removing excess carbon fouling or excess CLP during the cleaning process.
