Rags are a must have when cleaning guns. I use rags to not only wipe off my firearms but also to lay disassembled gun parts on and to protect guns from scratches from a hard tile floor or metal table. They also come in handy to wipe off your gun cleaning table when you’re done. I always take at least one rag to the range. They always seem to come in handy.
