I really like the little carrying case that it comes with, this allows you to throw the whole thing right into your range bag for a quick clean after shooting. I recommend getting this especially if your shooting non jacketed lead rounds. As the lead can build up in the barrel after a few hundred shots. This way you can clean your barrel at the range while its still warm before the lead solidifies, this cuts down on the use of heavier cleaning solvents at home.
