This unique tool is specifically designed for cleaning the lug recess area on AR-15 and .308 AR rifles. The lug recess area tends to accumulate significant amounts of grease and debris, necessitating regular cleaning. The tool functions by compressing a cotton roll, which is then released to allow for rotation within the lug recess area. It is recommended to use the tool with a solvent-soaked roll, followed by a dry roll for optimal results. Each tool is supplied with a bag containing approximately 50 cotton rolls. This device applies compression to a cotton roll, subsequently releasing it to facilitate rotational maneuverability within the lug recess area
